php mailer email something other than option value

php mailer email something other than option value

I have built a form on my site that acts as a quote calculator, a user
selects options, each option has a value and those values are added up and
displayed as the final quote. I now need to be able to email that form
which I'm doing using a php mailer.
The issue I'm having is that as far as I can tell, the mailer just sends
the value of the selected options, and not the name. Below is a snippet of
code from my form:
<form action="quote_mailer.php" method="POST">
// Some more select options... //
<select class="select" id="singerName" name="singerName">
<option value="0" name="first"></option>
<option value="195" name="jack">Jack</option>
<option value="195" name="james">James</option>
<option value="195" name="toni">Toni</option>
<option value="195" name="yvonne">Yvonne</option>
</select>
<input type="submit" value="Send"><input type="reset" value="Clear">
</form>
And for my php:
<?php
$name = $_POST['quote_name'];
$email = $_POST['quote_email'];
$number = $_POST['quote_number'];
$singerName = $_POST['singerName'];
$formcontent="From: $name \n Number: $number \n Email: $email \n Event
Type: $eventType \n Singer Name: $singerName \n Instruments:
$instruments";
$recipient = "sam.skirrow@gmail.com";
$subject = "Contact Form";
$mailheader = "From: $quote_email \r\n";
mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
echo "Thank You!";
?>
As you can see from the above code, in my email this returns "Singer Name:
195" as that is the option value, but I need it to return the option NAME
- is this possible?

Django cannot save postgresql instance on heroku

I am new to Django and Heroku. I just deployed my project following the
heroku documents. Part of settings.py is:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql_psycopg2',
'NAME': 'dfuldndi54p56q',
'HOST': 'ec2-54-227-251-13.compute-1.amazonaws.com',

'PASSWORD': 'Wp0Gjf66JEC4mRKkvKrF22ptnj'
}
}
# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] = dj_database_url.config()
part of models.py
class userInfo(models.Model):
"""The member information
"""
email = models.EmailField()
password = models.TextField()
account = models.CharField()
gender = models.CharField()
iconID = models.IntegerField()
gymID = models.IntegerField()
friendsNumber = models.IntegerField()
signature = models.CharField()
weibo = models.BooleanField()
in process.py:
try:
userInfo.objects.exists()
except DatabaseError:
user = userInfo()
else:
user = userInfo.objects.filter(email = email)
if user:
# check if the account is fully registered
if user.gymID:
return HttpResponse(content = 'user exist', status = 503)
user.email = email
pwmd5 = hashlib.md5(password)
user.password = pwmd5.hexdigest()
user.save()
after I push to heroku & syncdb, the following error occurred:

How to send an email via outlook with .asp

How to send an email via outlook with .asp

I'm not to familiar with this but i have done similar in the past.
Basically i want to have an html, or .asp page with a simple form for the
user to input data. I've accomplished this in VB.net with the following:
Imports Outlook = Microsoft.Office.Interop.Outlook
Private Sub cmdFax_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs)Handles cmdFax.Click
Dim oApp As Outlook._Application
oApp = New Outlook.Application()
Dim oMsg As Outlook._MailItem
oMsg = oApp.CreateItem(Outlook.OlItemType.olMailItem)
oMsg.Subject = ""
oMsg.Body = "" & vbCr & vbCr
If Len(txtEmail.Text) > 0 Then
oMsg.To = Me.txtEmail.Text
Else
oMsg.To = "[Fax:" & Me.txtAttn.Text & " @ " &
Me.txtFaxNum.Text & "]"
End If
Dim sSource As String = "C:\ValidPath.txt"
Dim sDisplayName As String = "Hello.txt"
Dim sBodyLen As String = oMsg.Body.Length
Dim oAttachs As Outlook.Attachments = oMsg.Attachments
Dim oAttach As Outlook.Attachment
If Len(Me.TextBox1.Text) > 0 Then
oAttach = oAttachs.Add(Me.TextBox1.Text)
Else
End If
oAttachs.Add(Me.cboForm.SelectedValue)
oMsg.Send()
oApp = Nothing
oMsg = Nothing
oAttach = Nothing
oAttachs = Nothing
'MsgBox("Your Fax Has Been Sent Successfully")
lblStatus.Text = "Fax Sent"
'lblStatus.Text = "Ready"
End If
End Sub
Is there anyway to accomplish the same thing using .asp? or is there an
easier way to do this using a contact form and .asp page? I'm just trying
to avoid using an external mail server and have the form send from the
actual user.
Open to any suggestions!

Message Length Zero and packet repeating

Message Length Zero and packet repeating

I am using an TinyOS application to send packets from Radio To Serial. I
am broadcasting messages. When I read motes using Java Listen class,
sometimes I receive packet length as zero and packet counter repeating
itself. What could be the problem? I get data something like this:
00 FF FF FF 01 12 3F 06 00 00 F7 54 00 00 F6 30 02 E0 00 18 27 6C 00 18 27 75
00 FF FF FF 01 12 3F 06 00 00 F7 55 00 00 F6 31 02 E0 00 18 27 82 00 18 27 8F
00 00 FF FF 01 00 3F 06 00 00 F7 57 00 00 F6 32 02 E0 00 18 27 98 00 18 27 AA
00 FF FF FF 01 12 3F 06 00 00 F7 57 00 00 F6 33 02 E0 00 18 27 B8 00 18 27 BD
00 FF FF FF 01 12 3F 06 00 00 F7 58 00 00 F6 34 02 E0 00 18 27 CE 00 18 27 D5
Here 00 00 F7 54, 00 00 F7 55 ... are my packet counters. So, if you see
this data, I have received packet length as '00' in third row and packet
counter repeating itself in 4th row. This happens sometimes only. If you
need I can post code too. Please help.

Why is headhunting uncommon for academic positions? –

In scientific conferences, there are usually many headhunters who come to
offer newly graduated scholars jobs in the industry sector. As a matter of
fact, the recruitment in industry mostly works with …

Evaluate $ \lim_{x\rightarrow{\frac\pi2 }} (\sec(x) \tan(x))^{\cos(x)}$

I have tried changing limit to $\lim_{x\rightarrow0}$ and use some
trigonometry identity ($\sin^2(x)+\cos^2(x) = 1$ and $\sin (x+\pi/2) =
\cos(x)$) but doesn't work I have no idea on how to do this …

How to show that $(\delta'f)(e)=\delta(\phi^* f)(e)$?

How to show that $(\delta'f)(e)=\delta(\phi^* f)(e)$?

I am reading linear algebraic groups.
I have a question in line 4 of the third paragraph of Page 66. How to show
that $(\delta'f)(e)=\delta(\phi^* f)(e)$ for all $f\in K[G]$? Here $G$ is
an algebraic group, $K$ is an algebraic closed field, $\delta' =
\operatorname{Ad} x(\delta) = d(\operatorname{Int} x(\delta))$,
$\phi=\operatorname{Int} x$, $\operatorname{Int} x(y) = xyx^{-1}$, $x, y
\in G$. Thank you very much.
I think that $\delta'f = d(\operatorname{Int} x(\delta))f$.

Remove x amount of elements with .remove()

Remove x amount of elements with .remove()

I am not seeing any clear documentation on removing a certain amount of
elements without it being in a specific order, of course there are many
ways to remove a list of say 5 items, if they are in that order. What if
there is elements that you don't want removed in between? Let me show you
an example
FIDDLE: Below is just pieces from this fiddle, it would be easier just
taking a look at the fiddle.
HTML
<div class="item empty">Empty</div>
<div class="item empty">Empty</div>
<div class="item editable">Editable</div>
<div class="item empty">Empty</div>
</div>
<button class="demo">Demo</button>
jQuery
$('.demo').click(function() {
var length = $('.item').length,
columns = 12/6,
addColumn = columns - length
//Set this for subtracting elements if addColumn is a negitive
if(addColumn < 0) {
//Want to remove the amount of items which is -2 in this case
$('.item.empty').eq(/*Remove whatever amount of addColumn */ ).remove()
}
//Equals -2
alert(addColumn)
});
So just to be clear, I am trying to remove the amount of .empty items
based on whatever the amount is passed into the addColumn variable in this
case its static set at -2.
So I ask if addColumn < 0 is a negative number then we do subtraction
using .remove() and I need to remove the amount of .empty items equal to
the addColumn variable.
12/6 comes from a 12 column grid and the 6 is a two column layout span6
span6 and so if the layout is set at 4 columns we need to remove 2
columns, which is where the -2 comes from.

Getting div id by GET in Javascript

Getting div id by GET in Javascript

Ciao
I need to create a dynamic form based on user selections.
I.e. in the first form field I select "John Smith", this will populate
(through an external php/mysql file ) the second select field "Artist,
Carpenter, Other", if I choose Artist I populate the third select field
with "Singer, Painter, Sculptor" and so on
Giving my incompetence on javascript, I spent the morning googling for
scripts and I found a cool tutorial here
It works, it's clean, but it updates only the div with id txtResult, which
is statically included in the js file (see lines 19 and 31 of
ajax_req.js). I thought I could pass the id name by GET, but I don't know
how to make the script recognize the variable.
This is the code:
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtResult").innerHTML=
xmlHttp.responseText;
}
}
I had in mind to pass by GET the id name and have something like this:
function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("GET[idName]").innerHTML=
xmlHttp.responseText;
}
}
Can you please help me? I could change script too if you happen to know
something better
Ciao and thank you,
Ed

SQL- Getting maximum value along with all other columns?

SQL- Getting maximum value along with all other columns?

I have a table, which can be seen as a evaluation of two courses in
several classroom tests, like this:
student_ID Evaluation Course1 Course2
------------------------------------------------------
1 5 88 93
2 4 70 87
1 5 93 90
2 5 99 91
3 3 65 60
3 4 88 70
I need to get the result of the Evaluation=5 for each student, if any. If
that student has more than one Evaluation=5, the query only show any one
of them. So for the above example table, the query result will be
student_ID Evaluation Course1 Course2
------------------------------------------------------
1 5 88 93
2 5 99 91
Of course in my real table, the "Courses" number is more than 2.
Thanks for the help.

How to create FlexSlider with flipping content

How to create FlexSlider with flipping content

I'm starting to get in to web development. I'm keenly interested on
minimal designs and flat UIs.
I was googling around and found some interested sites. This particular
site caught my eye which has a unique slideshow. I did a bit of snooping
with dev tools and found that the site uses Flexslider.
I would really like to know how to achieve this kind of effect.
A sample on Fiddle with 2 image slides with flipping content would be
really appreciated if possible to be provided.

How to increment a single number in a text file with PHP

How to increment a single number in a text file with PHP

I am writing a VoteBox (like/dislike box) in html and I cannot find how to
do this anywhere.
Basically, there will be a like and a dislike button. When one of them
gets clicked, it will forward the user to a page. And in that, I want some
PHP code that will increase the number in upvotes.txt/downvotes.txt
I have tried doing it with a database but the problem is I want anyone to
be able to use this without any setup.
i also want the front page to display the number of upvotes and the number
of downvotes
so its kinda like this (most of this isn't real code BTW im new to PHP):
//this is the code for upvote.html
$upvotes = get_data_from_TXT_file
$changedupvotes = $upvotes + 1
set_data_in_txt_file_to_$changedupvotes
Sorry if i havent explained this very well
Any help appreciated

Pretty new to Java, how to insert user-inputted string to direct a reference?

Pretty new to Java, how to insert user-inputted string to direct a reference?

(In java,) This may or may not be possible, I assume it is because it
seems to short-cutty/easy to not exist. Basically what I want to do is
have the user insert the name of a state, then it add one to that state's
counter, which is stored in a different class. I want to do this without
creating 50 if/else statements. Here's pseudocode which represents how I
would expect it to be done. (this code would be encapsuled in a while loop
in mainclass.java and the counters and state names are in a class named
state.java.)
Scanner userstate = new Scanner(System.in);
String statename = userstate.nextLine();
state.(statename).counter++;
in state.java:
public state(int counter){
}
public static state Alabama = new state(0);
For time's sake, I hope there is a shortcut similar to the above.

ASP.NET MVC application that needs reading from SQL server not working on
IIS but on visual studio, while ASP.NET Web Applicatopn worked for...

I followed an example of using SQL databse from an ASP.NET MVC application
and can get it work on Visual Studio, but when I tried to deploy it on the
local IIS and provide the values on the URL it was said "... The resource
cannot be found.
Description: HTTP 404. The resource you are looking for (or one of its
dependencies) could have been removed, had its name changed, or is
temporarily unavailable. Please review the following URL and make sure
that it is spelled correctly. ..."
I can access the same SQL database from APS.NET Web application but not MVC.
Can you tell me why this happens and how to solve the problem?
