Dynamic form elements

[trufla]

Hiya!

I am trying to write a script that [a] asks a user how many input elements they require for a form, and the names of those input elements.

I am completely stuck! I did this first for the dynamic generation:

<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="POST" >

<input type='text' name='inputfield'/></p>

<input name="inputname" cols="50" rows="25"></textarea>

<input type='submit' name='submit' value='Submit' />





<? php

if(isset($_POST['submit'])){

 $required = $_POST['inputfield'];

 $x = 0;
 while ($x <= $required){
 echo "<p><input type=\"text\" size=\"25\"</p>?>";
 ++$x;
 }

 elseif(empty($required)){
 echo "<p>Please enter an input element count.</p>";
 }


}


?>

I keep returning the error:

Parse error: parse error, unexpected T_IF

I had a think about how to get names for input elements from users. I thought about using:

$inputnames = $_POST['inputname'];

$chars = preg_split('/ /', $inputnames, -1, PREG_SPLIT_OFFSET_CAPTURE);
//Where user has specified names into the text area of the previous code.

I thought about putting the $chars values into their own variables, but I do not know how to create dynamic variables.

This is a mess at the moment!

Could any of you peeps see a better way?

Any help appreciated!

Well.. It mentions the error: It did not expect to find an if statement. Please next time add the line nnumber on which the error occured. In this case, you have :

Open IF statement
Open WHILE loop
Close while loop
open else statement // Just before the elseif you need a curly bracket 'close'

Furthermore.. If you cannot figure this one out.. Do you think it wise to start programming a form-creation module?

But, ok. What you could / should consider.. Ask how many fields, post that, create a new form, with a textbox for each field, created with an array as name
(<input type=text name=fieldname[]>)

Then the names are returned to you as an array in the post. Having them upload it as a list froma textbox is possible, but you run into issues like dealing with spaces in names etcetc.

Of course, if the whole thing is to be automated (SO you create processing of the form etc on thy fly too), then you do not need to have usr-defined names, as the internal functioning is not of concern to the user...
