Help with (simple?) "foreach"..

[Incredinot]

Alright... Im getting some errors with my foreach loop..

Can anyone tell me whats wrong with it?

 

It does print like it should correctly, but i get this error also:

Invalid argument supplied for foreach() in C:\xxxxx\xxxxx\xxxxx on line xxx.

 

Note: It do print the things it's supposed to - but the error comes anyway? o.O

 

Here is the code:

<?php foreach($field_foo as $hai) {print $hai['value'] . ", ";}?>

 

And i will also like to write ", " while there is more.. But if its the last, i just want a ".".

 

Hope you understand (:

Providing $field_foo is an array (which the error suggests its not), it would be much simpler & more efficient to use implode.

 

<?php echo implode(', ', $field_foo); ?>

First check you array $field_foo, is it valid array?

 

Then for "," issue here is the code

<?php
$str = "";
	foreach($field_foo as $hai) {
		$str = $hai['value'] . ",";
	}
	$str = substr($str,0,-1);
	print $str;
?>

<?php echo implode(', ', $field_foo); ?>

 

If i use the above code, it just print "Array, Array, Array, Array "

And if i write something like:

 

<?php echo implode(', ', $field_foo['value']); ?>

i get nothing..

$field_foo is obviously a multidimensional array then. What is the output of.....

 

print_r($field_foo);

 

?

Dont really know what your array looks like but see if this works.

 

<?php 
$i=1;
$num=count($field_foo);
foreach($field_foo as $hai) 
{
if ($i != $num)
{
print $hai['value'] . ", ";
}
else
{
print $hai['value'] . ".";
}
$i++;
}
?>

This is what i get from:

<pre><?php print_r($node->field_spillesteder);?></pre>

 

Array
(
    [0] => Array
        (
            [value] => Vestjylland
            [safe] => Vestjylland
            [view] => Vestjylland
        )

    [1] => Array
        (
            [value] => Nordjylland
            [safe] => Nordjylland
            [view] => Nordjylland
        )

    [2] => Array
        (
            [value] => Sjælland
            [safe] => Sjælland
            [view] => Sjælland
        )

    [3] => Array
        (
            [value] => Fyn
            [safe] => Fyn
            [view] => Fyn
        )

)

So, what exactly do you want as output? Its obvious these array element can't simply be joined by a ,

[Incredinot]

Alright, let me explain (:

 

I have this "page".

 

When i create a page i have a select box where i can select different things.

 

To be exact it is:

 

Sydjylland

Vestjylland

Midtjylland

Nordjylland

Sjælland

Fyn

Bornholm

 

In the above example, i have chosen "Vestjylland, Nordjylland, Sjælland, Fyn".

 

Now i want to output that this it what i have chosen.

 

Hope you understand

Can we see the code for the select?

[Incredinot]

<select multiple="multiple" name="field_spillesteder[value][]">
<option value="Sydjylland">Sydjylland</option>
<option selected="selected" value="Vestjylland">Vestjylland</option>
<option value="Midtjylland">Midtjylland</option>
<option selected="selected" value="Nordjylland">Nordjylland</option>
<option selected="selected" value="Sjælland">Sjælland</option>
<option selected="selected" value="Fyn">Fyn</option>
<option value="Bornholm">Bornholm</option>
</select>
