I have designed a survey with PHP that submits the responses into a MySQL database. The people that will be taking the survey are existing clients which have user IDs and information stored in a database that I do not have direct access to.

What I would like to do is send each client an email with a link that sends their id number with their survey responses.

I have two variables that I need to pass with the link: center and custID - I was planning on doing it like so...
.../pre_venture.php?center=10&custID=1...

When they click the link, I need the values passed with the survey responses. I have two files pre_venture.php and presurvey.php... pre_venture is the actual survey and presurvey is what sends the information into the database.

In the presurvey.php file, I use post to send the information to the database like so...

$sql="INSERT INTO pre_vent (center, custID, yStart, yAcquired, yOther, comments)
VALUES
('$_POST','$_POST[custID]','$_...

When I test the survey, the values for center and custID are not sent. Please help!

Try $_GET instead of $_POST to get parameters every time you use URL method.

Also, try to remove the single quotes on the SQL query. Use it on the array index.

$sql= sprintf("INSERT INTO pre_vent (center, custID, yStart, yAcquired, yOther, comments)
VALUES
('%s','%s', ... )", 
   mysql_real_escape_string($_GET['center']),
   mysql_real_escape_string($_GET['custID']),
... );

Thanks but I still am not having any luck... here's the code in its entirety for both files... also here's a link to the survey page...

Here is the code for the actual survey....

I'm new to PHP and have been trying to learn it from the w3schools website.. obviously I have a lot to learn..

anyway, thank you for your help

I'm looking at your code, the method used in your form and mysql variables is ok, but into the form code, the survey code is commented into <!-- ... --> tags, remove it.

Add value="<?php echo $_GET['center']?>" into the input tags, should be something like:

<input type="text" maxlength="2" size="3" name="center" value="<?php echo $_GET['center']?>" />-<input type="text" name="custID" maxlength="5" size="10" value="<?php echo $_GET['custID']?>" />

Now, you can use /pre_venture.php?center=10&custID=1 in your link

If you want to hide that input elements, use this instead of above code:

<input type="hidden" name="center" value="<?php echo $_GET['center']?>" />
<input type="hidden" name="custID" value="<?php echo $_GET['custID']?>" />

On the PHP submission code, you use only $_POST instead of $_POST['center'] on the first value. Is that ok?

commented: Good post. You could have also mentioned the use of the $_REQUEST since she is mixing both $_POST and $_GET usage in her page. +2

Thank you!! It works perfectly! You are awesome!
