Passing Variables Through Link

[srarcade]

I have a simple form like this:

<form method=POST>
File Type: <select name="ftype" size="1">
		<option value="0">Choose...</option>
		<option value="1">Image</option>
		<option value="2">Website</option>
		<option value="3">Flash</option>
	</select><br></form>

And a simple link like this:

<? echo"<a href=\"upload2.php?ftype=$ftype\">Next</a><br>";

My question is, why can't the link grab the form data for $ftype and post it to the URL? It always shows up as 'upload2.php?ftype=" The same thing as if I were to make it a submit button, but I'd rather use a link.

Thanks!

PHP is a server side language, so there's no way of knowing what $ftype is without first submitting the form.

So, the reason your link is coming out as "upload2.php?ftype=" is because $fypte holds nothing until you submit the form.

You could use Javascript to auto-submit the form when the select box has changed values, which would in turn update your link properly.

You could also make the form submit when the link is pressed:

<form name="myForm">
Please select: <select name="fname">
    <option value="1">First
    <option value="2">Second
    <option value="3">Third
</select>
</form>
<a href="javascript: document.forms['myForm'].submit();">Next...</a>

Well what i am trying to achieve is this:

I have a download page now where a user fills out all the info and submits it. I want to change it so the information is filled out 1 query at a time over a series of 5 pages. The data from the each page is carried over to the next until the last page where all that data can be confirmed, then inserted into the database. I could do this if i made a temporary data storage table for each user but id rather keep it in the browser.

Maybe i should use it in the session data?

use hidden inputs

foreach($_POST as $key => $value) {
   echo "<input type=\"hidden\" name=\"$key\" value=\"$value\">\n";
}

Do that on each page within your form fags and it will create hidden inputs that you'll have access to all the variables filled out on each of the 5 pages, and access to all the variables by page 5.

Thanks, that was just the code i was looking for!

no problem. loops are the way to go. I used to manually type that out on each page (and manually type out code for other things). when I discovered loops, I literally started to save HOURS!

Glad you got it working.
