Newbie form variables question?

[Anon]

Hi Guys. I am a newbie to php and am trying to send the values of my form to the restults page so the user doesn't have to type all form variables again.

Is there a way of doing this?

Thanks Ian.

If you submit a form, and it has variables filled out, they automatically go to the resulting page.

Suppose you ask the user for input

<INPUT TYPE='TEXT' NAME='varname'>

On the resulting page, if you want to display that input box again with the value, just do this:

<INPUT TYPE='TEXT' NAME='varname' VALUE='<? echo $varname; ?>>

Yes; see the section in the manual on "Variables from Outside PHP". To cut the story short, $POST[] or $GET[] are arrays containing the form-supplied data (which one you use depends on what method your form uses).

If a (POSTed) form has an element named "foo", then $_POST['foo'] will contain the submitted value of the element.

for text inputs:
<input type="text" name="whatever" value="<?= $whatever ?>">

for checkboxes or radios:
<input type="checkbox" name="whatever" value="whatever"<? if ($whatever) {echo ' checked';} ?>>

for selects:
<select name="whatever">
<option<? if ($whatever == 'someoption') {echo ' selected';} ?>>someoption
</select>

for the selects it is much easier to put all of your options into an array or db and loop thru.

Only if you want to encourage bad coding practices.

Is it true that they are forcing the use of those arrays come the next version of PHP? It's funny, because I never learned to do it that way - even the books I learned from originally did not do it this way.

Ian,

You did say much on what-where-how the variables are being sent.
so I'll just give a small sample script.

//**** snip
<?php
if ($submit)
{
echo "your variable is $var ";
}
?>

<form>
<input type="text" name="var" value="<?=$var;?>" size=20>
<input type=submit name="submit" value="test"></form>

//***snip

hope this helps

They are now; register_globals is turned off by default from PHP4.1 on. For security and performance reasons described in the manual.

You realise of course that if Ian is new to PHP, and has a new version of PHP, the next question will be "I tried that and it doesn't work. Why not?"

lol of course I do! <grin>
