Help With Array

[limitphp]

I have a form submitting an unknown number of textboxes named:

fname1, fname2, fname3, etc....

 

How do I capture the values?

I figure using an array would be easiest....

 

$i=1;
$fname = array();	
while ($i<=$num)
{
	$fname[$i] = $_POST['fname'.$i];

	$i++;
}
$i=1;
while ($i<=$num)
{
	echo $fname[$i]." ".$lname[$i]." ".$position[$i]."<br><br>";
	$i++;
}

 

This doesn't seem to be working...

its not showing anything....

Why don't you name all of your textbox the same thing "fname[]".

 

Then in your processing script you can just do:

 

foreach($_POST['fname'] AS $fname)
   echo $fname;

try something like this:

 

$i=1;
$fnames = array();

foreach($_POST as $fld=>$val){
    if(eregi("fname",$fld)){
    $fnames[$i] = $val;
    $i++
    }

}
$i = 1;
foreach($fnames as $fname){
   echo $fname[$i]." ".$lname[$i]." ".$position[$i]."<br><br>";
   $i++;
}

actually, I'll need to do more stuff than just echo them...I'll need to add the values to a database...and there will be more than just fname...there will be lname and position as well.

 

So, if I change the textboxes to fname[], lname[], and position[]

also, I'll know the exact number....from $num....

 

how would I grab each value?

ex)

 

loop (as many times as $num)

{

  do stuff to each value of fname, lname and position

}

 

thanks...

I read this on php.net:

 

 

Many web sites do this:

<form ....>

<input name="person_0_first_name" value="john" />

<input name="person_0_last_name" value="smith" />

...

 

<input name="person_1_first_name" value="jane" />

<input name="person_1_last_name" value="jones" />

</form>

 

//Which is exactly what i was trying to do, because I do not know any BETTER....

 

When they could do this:

 

<form ....>

<input name="person[0][first_name]" value="john" />

<input name="person[0][last_name]" value="smith" />

...

<input name="person[1][first_name]" value="jane" />

<input name="person[1][last_name]" value="jones" />

</form>

 

With the first example you'd have to do string parsing / regexes to get the correct values out so they can be married with other data in your app... whereas with the second example.. you will end up with something like:

<?php

var_dump($_POST['person']);

//will get you something like:

array (

0 => array('first_name'=>'john','last_name'=>'smith'),

1 => array('first_name'=>'jane','last_name'=>'jones'),

)

?>

 

I sort of understand what they are saying, but not quite....

 

How would I apply that to what I'm doing?

Can someone help me?

 

I didn't know arrays could get that complicated....

Would I need to do a foreach loop for each fname, lname, and position?

Or is there a way to combine all of them in one loop?
