form question..

[ag3nt42]

hello,

 

I have a question how form inputs.. its not php code persay but this seems like the suitable forum to ask the question and I will be using it inside php so..

 

I kno that on a multiple selection query you can use \[\] at the end of the name and that makes it send the information as an array.

 

Now my question is can you do that same thing with a regular text input?

 

sorta like :

<input type='text' name='tall_chicken[]' value='' />

<input type='text' name='tall_chicken[]' value='' />

<input type='text' name='tall_chicken[]' value='' />

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

 

then can you catch it the same way like:

 

<?php

if(isset($_POST['tall_chicken']))
{
$count=count($_POST['tall_chicken']);

for($x=0;$x<=$count;$x++)
{
  $Chicken[$x]=$_POST['tall_chicken'][$x];
}
}

?>

i knew somone would say that... lol..

 

no i didn't.. I didn't want to have to change all of this code around just to try something that might or might not work ya. know.

well aside from the fact that you don't have form tags, that should work just fine.

 

edit:

 

though, I'd personally use a foreach loop instead of counting and using a for loop.

Also fyi, the array will always go from 0 to whatever, even if you clicked say, the 2nd and 3rd option, but not the first, the array elements will still be 0-1 not 1-2.  Or if you entered in something for #1 and #3 the posted array will still be in positions 0 and 1 not 0 and 2.  If for some reason you need to know what position they are in on the form, you need to specify an array position not just do [] in your form.

"huh" as in you don't understand? or "huh" as in "that's interesting" ?

[ag3nt42]

as in ???

 

i don't understand what your talking about sry.

What they mean is, the first value of $array is $array[0], the second is $array[1] etc. etc.

Basically, the first is 0, not 1

well but I'm also saying that if you have 3 fields and fill out all 3 of them, your posted array positions will be:

 

$_POST['tall_chicken'][0]

$_POST['tall_chicken'][1]

$_POST['tall_chicken'][2]

 

but if you only put text into say, field 1 and field 3, it will not be positions

 

$_POST['tall_chicken'][0]

$_POST['tall_chicken'][2]

 

it will be

 

$_POST['tall_chicken'][0]

$_POST['tall_chicken'][1]

 

[ag3nt42]

oh well i'm not really worried about the positions of them.. I'm only using them to submit data at this point.. and they will not need to get values placed back into them.

 

 

thankx tho.. I think I got her working.
