PHP Form redirect

[cchhita]

Hi There,

I have a problem with a form redirect I am trying to achieve.

I am trying to redirect a user to a certain page depending on what they select from a dropdown menu.  This seems quite straight forward, but I am trying to past a value that the user enters into the page as well, this is where I am having the problem.

 

Here is my HTML Form:

<form action="jump.php" method="post">
  <p>
  <!-- Zip Code -->
  ZIP code:
  <input type="text" size="5" name="zip" id="zip" onBlur="updateCityState();"/>
<select name=url>
<option value="http://www.mydomain.com/forms/form1.php">Option1</option> 
<option value="http://www.mydomain.com/forms/form2.php">Option2</option> 
<option value="http://www.mydomain.com/forms/form3.php">Option3</option> 
</select>
<Input Name="submitButton" Value="Submit" Type="Submit"/></p>
</form>

 

Jump.php code

 

<?php
$sZipCode = $_POST['zip'];
$url = $_POST["url"];
header("Location: $url");
?> 

 

I have tested the code, and I am able to send the Zip Code from the HTML form to the Jump.php page without any problems.  But when the jump.php executes, it does not carry the Zip Code Value to the page, but the redirection works correctly and goes to the right page.

 

Can someone please tell me where the error in the code is?

Or am I missing something?

 

Thanks

you could set 'zip' as a session variable inside, then it would carry across as long as the session is started on each page.

or append the zip code to the url and get it through get.

<select name=url>
<option value="http://www.mydomain.com/forms/form1.php">Option1</option> 
<option value="http://www.mydomain.com/forms/form2.php">Option2</option> 
<option value="http://www.mydomain.com/forms/form3.php">Option3</option> 
</select>

 

Try rewriting this as:

<select>
<option name=url value="http://www.mydomain.com/forms/form1.php">Option1</option> 
<option name=url value="http://www.mydomain.com/forms/form2.php">Option2</option> 
<option name=url value="http://www.mydomain.com/forms/form3.php">Option3</option> 
</select>

 

Im really not sure if this will make a diffrence but I am somewhat curios about it.

As far as I am aware, you aren't able to pass $_POST arguments between pages that aren't directly in use for the form. The easiest way would be as mentioned above. Add it to the url and access it via $_GET later on. You can do this like this:

 

$sZipCode = $_POST['zip']; 
$url = $_POST['url']; 
$parsedUrl = $url.'?zip='.$sZipCode; 
header("Location: $url");

 

You can then access it on the next page like this:

$zip = $_GET['zip'];

Hi There,

Thanks for the input everyone!

Xangelo, I have taken your code and make one little change. 

 

Here it is:

$sZipCode = $_POST['zip']; 
$url = $_POST['url']; 
$parsedUrl = $url.'?zip='.$sZipCode; 
header("Location: $parsedUrl");

 

When I tried just URL, it would not work, when I plugged in $parsedURL I got the result I wanted.

 

I tried to extend this example, but not am having a problem.

I want to pass 3 variables to the page, i.e. ZIp, City and State.

 

I thought I could do this simply by concatenating the extra variables from my first form into the jump form, and passing those variables as a GET into my third form, but this does not work.

 

Here is my code now:

 

<?php

$sZipCode = $_POST['zip']; 
$sCity = $_POST['city']; 
$sState = $_POST['state']; 
$url = $_POST['url']; 
$parsedUrl = $url.'?zip='.$sZipCode.'?city='.$sCity.'?state='.$sState; 
header("Location: $parsedUrl");
?> 

 

When I pass these values to my form, in the Zipcode box, I get all the variables in one String, i.e. 60601?city= Chicago?state= Illinois

 

How do I pass the variables to the correct boxes in my form?

 

Thanks

Sorry about that cchhita.. I meant to put down $parsedUrl, but I was just a little distracted at the time I suppose.

 

You're on the right way to adding more variables, but you need to alter it ever so slightly:

<?php

$sZipCode = $_POST['zip']; 
$sCity = $_POST['city']; 
$sState = $_POST['state']; 
$url = $_POST['url']; 
$parsedUrl = $url.'?zip='.$sZipCode.'&city='.$sCity.'&state='.$sState; 
header("Location: $parsedUrl");
?> 

That should work fine for you. Only one questionmark should appear in the url, adding more variables means they are separated by an ampersand (&).

Works like a charm!!

Thanks for the very quick reply.  I knew I was on the right track but had something small wrong!

 

Thanks again!

Not a problem, glad to be of some help.
