seperating form values with arrays!!!

[Monkuar]

This is really cool if I can get it to work

 

My PHP CODE:

 

$ids = implode (",", $ibforums->input['checkbox']);

 

Grabs from this data in my HTML FORM:

 

<input name="checkbox[]"  type="checkbox" value="{$r['id']},{$r['friendid']}">

 

 

Now when I pass my input, I will get 2 different values in both array's how do I separate them out? I know how to seperate them out using implode, but I need to seperate BOTH of the array's that are being passed, and I need to use them separately.

The counter part to implode, explode.

 

So if the value of checkbox is "1,2" and you run explode( ',' '1,2' ); you will get a value of array( 1, 2 );

 

if you want to split the entirety of the checkbox i'm pretty sure:

 

<?php

$idArray = array();
$friendIdArray = array();

foreach( $ibforums->input[ 'checkbox' ] AS $key => $val )
list( $idArray[], $friendIdArray[] ) = explode( ',', $val );

 

Now you should have two separate arrays of values with corresponding array keys.

What? There is only ONE array: $_POST['checkbox']

 

The values of those array elements are simple a string with what appears to be two numbers separated by a comma. I don't know why you would want to implode the POST data. I would think you would want to run a foreach() loop on the checkbox array and then explode the value on the comma to get the two unique IDs and then perform an operation on them.

 

foreach($_POST['checkbox'] as $postVal)
{
    list($id, $friendid) = explode(',', $postVal);
    echo "ID: {$id}, Friend ID: {friendid}<br>\n";
}

    echo "ID: {$id}, Friend ID: {friendid}<br>\n";
}

 

it's not returning them seperated in " , " tho?

 

 

foreach($ibforums->input['checkbox'] as $postVal)
{
    list($id, $friendid) = explode(',', $postVal);
echo $friendid;
}

 

this will result in

 

echoing " 302 "

 

which is actually supposed to be 30,2

 

but i tried implode/explode the $friendid again and it's not working

the $id and $friendid do work and show both arrays, thank you, now i just need to stick a , between em

Then something is NOT as you say it is. According to you the checkboxes are created like this:

<input name="checkbox[]"  type="checkbox" value="{$r['id']},{$r['friendid']}">

 

So, if you had three checkboxes with various values, they may look like this

<input name="checkbox[]"  type="checkbox" value="5,31">
<input name="checkbox[]"  type="checkbox" value="12,8">
<input name="checkbox[]"  type="checkbox" value="5,7">

 

If the user checked all those boxes the resulting POST array would be

[`] => "5,31",
[1] => "12,8",
[2] => "5,7"

 

That is an array with three string values. If you iterate through that array you can explode each value using the comma to get the two unique values. The code I provided should do just that - if your checkboxes are in the format you say they are.

Yeah the array is not working though, if I use [1] like $id['1'] it only spits out the first character. I am using it inside the list function also.

 

This is my current code:

 

foreach($ibforums->input['checkbox'] as $postVal)
{
    list($id, $friendid) = explode(',', $postVal);
echo $id;
}

Exactly what you gave me, here are my checkboxes that a user will check (for instant)

 

 

<input name="checkbox[]" onclick="check(this)" type="checkbox" id="checkbox[]" value="3,30">

<input name="checkbox[]" onclick="check(this)" type="checkbox" id="checkbox[]" value="1,2">

 

 

So we should be getting 3 and 1 right?

 

I check those 2, and your code gives me:

31

 

which is right, it's getting 3 and 1, but i need it to be 3,1 which it is not displaying.

 

Thank you,

$idArray = array();
$friendIdArray = array();

foreach( $ibforums->input[ 'checkbox' ] AS $key => $val ){
   list( $idArray[], $friendIdArray[] ) = explode( ',', $val );
}

echo implode(',', $idArray);
echo '<br>';
echo implode(',', $friendIdArray);

 

[Monkuar]

$idArray = array();
$friendIdArray = array();

foreach( $ibforums->input[ 'checkbox' ] AS $key => $val ){
   list( $idArray[], $friendIdArray[] ) = explode( ',', $val );
}

echo implode(',', $idArray);
echo '<br>';
echo implode(',', $friendIdArray);

 

NOW THAT"S WHAT IM TALKING ABOUT!!!

 

WOW, Did not know you could freaking pass 2 array's in a value=XX this is great news LOL!!! man I bet I could even go up to 3-5 arrays eh? This is great news!! this code will be saved/etc so I can use in the future, thank you somuch, you just made my life 50% easier.
