How to print an array of $POST

Hi all


This is probably the easiest question ever , but I am not familiar with arrays , so hope somebody can help me


User post this checkbox form (array):

<input type="checkbox" name="type[0][]" value="1" >
<input type="checkbox" name="type[0][]" value="2" >
<input type="checkbox" name="type[0][]" value="3" >

I need to get all checked values and print them ...
How can I do this?


I tried the code below, but it only returns me one value

$values = array($_POST["type"]);

foreach ($values as $item){

     echo $item;

}

Code (markup):

Any help???



Thanks!!

 

$values = array($_POST["type"][0]);

foreach ($values as $item){

     echo $item;

}

PHP:

might work

try what axelay posted but for an explanation of why its not working. Your only getting 1 value because it is a multidimensional array. So when you say foreach it is looking at the [0] you have, it looks for type[0], type[1], type[2].....and so on. You only have type[0] so it returns that first 1 and stops.

 

I believe that this is what you are looking for:

<?php
function print_array($array)
{
print_r($array);
}

Code (markup):

Then all you need to do is pass $_POST to that function like this:
print_array($_POST);

 

That would print everything in $_POST though, if all he has is the check box array then that would work but if there is more form fields its going to print it all, not just the check box array.

 

ow, thanks for the great tips
the axelay solution worked perfectly
and the print_r is very useful

 

One last thing:
I need to use this is a sql query.
When I place this information into my WHERE condition, I get the last value

How to get them as differents variables? should I use "for" instruction?!

$values = array($_POST["type"][0]);

foreach ($values as $item){

     echo $item;
     $where_str = " AND gu.id_item='".$item."' ";
}

Code (markup):

 

I think your query should be in foreach loop

 

Hi all

Finally I got it working!
I had to use "OR" instead of "AND"

Thanks to all who helped me
