How to insert GET variables into a HTML form

**Atli** · Sep 6 '07, 04:05 PM

Hi Steve.

I moved your question into it's own thread in the PHP forum, where it is more likely to be read by our Experts.

I've also added [code] tags to your post. All code should be encapsulated in code tags.

Using PHP, you could change your hidden <input> tag to look something like the this:
[code=php]
<input type="hidden" value="<?php echo $_GET['leadID']; ?>" name="Lead ID">
[/code]

This is assuming that your URL contains the GET variable 'leadID'. So your URL string would have to look something like this:

Code:

http://myserver.com/mypage.php?leadID=valueOfLeadID

I am using this also to pull a field called contact which contains the full name of a person. When it places the value in the text box, it only puts the first name and not the full name. Here is the code I am using for this:

[code=php]<p><input type="hidden" value=<?php echo $_SERVER['QUERY_STRING']; ?></p>
Contact: <input type="text" name="Contact" value=<? echo $_GET['contact'] ?>>[/code]

Can you post the full URL string you used for this?

**steve2856** · Sep 6 '07, 08:12 PM

Variables1.php? contact=Mark%20 Twain

Try urlencode() first. if not working please post back.

Is this the correct syntax:
[code=php]
<input type="text" name="Contact" value=<? echo $_GET[urlencode('cont act')] ?>>
[/code]

I only get the problem of truncation when the variable is passed to a text field. It does not truncate when I just display the value on the screen. What would be the difference?

How is the URL string being generated?
Are the values being passed from a HTML form?
Or are you generating the URL with some PHP code and echoing it as a link? (Or redirecting perhaps?)

If it is being generated from a HTML form, consider changing the 'method' to POST, which is a far better method for passing on detailed information, such as full names.
You can access those values just like you would the GET values by using the $_POST array.

The URL string is being placed as a hyperlink in an E-mail message. Once this link connects to the page, it displays information including the contact full name in a text box. For some reason, when I do this as just a display without populating a text box, all is fine.

I see.

This would be the line that is causing the problem?
[code=php]
<input type="text" name="Contact" value=<? echo $_GET['contact'] ?>>
[/code]

Try putting the value inside quote marks and see what that does. (And to follow the standards, close the tag as well).
[code=php]
<input type="text" name="Contact" value="<? echo $_GET['contact']; ?>" />
[/code]

If that doesn't work, you can try running it through the urldecode() function:
[code=php]
<input type="text" name="Contact" value="<? echo urldecode($_GET['contact']); ?>" />
[/code]

That did the trick...Thanks! !
