Autofilling Forms with Post Data

stevenmusumeche

Hi,

I know how to fill a form with post data.

However, how do I do this for a form that has an array as it's name?

For example:


  for ($i=0;$i<20;$i++)
      echo "<input type=\"text\" name=\"GE_Vis_Rep[]\" size=\"3\">";

This form posts to itself (<form action="<? echo ($_SERVER['PHP_SELF'])), and I'd like to have the previously entered values of the form be filled in on POST. Any ideas? Please let me know if my question is unclear.

lets say you have a select box like below that will have multiple choices so you want all choices displayed on next page

now on the php page you can do something like

$selectbox = $_POST['selectbox'];
$selectbox = @implode(", ", $selectbox);
echo $selectbox;

that will print, if you choose 2, 3, and 4 like

2, 3, 4

voila

you get the idea if not read up on

www.php.net/implode

and

www.php.net/explode

Maybe I wasn't clear enough. I have this in my loop:

<input type="text" name="GE_Vis_Rep[<?=$i?>]" size="3">

But I want to make it so that the value field is like this:

value="<?=$_POST["GE_Vis_Rep[$i]"] ?>"

I get an undefinded index, even when $_POST["GE_Vis_Rep[0]"] has a value. Any ideas?

Have you tried foreach(if i understood your problem right)?

 foreach ($variable as $something) {
       echo " <option value=\"$something\">$something</option>";

Take I look at http://pt2.php.net/manual/en/control-structures.foreach.php

Hope this helps 🙂

Cheers
