I thought of a while loop but cant find the way around this:
$foo1 = get_post_meta( $post->ID, '_item1', true );
if (!empty($foo1)){
echo ("<div class='$foo1'></div>");
}
$foo2 = get_post_meta( $post->ID, '_item2', true );
if (!empty($foo2)){
echo ("<div class='$foo2'></div>");
}
And so on... for a hundred times until I reach $foo100 and _item100 Any idea to achieve this to not repeat these 4 lines over and over?
You don't need variable variables for that, but just a for loop like this:
for( $i=1; $i<101; $i++ ) {
$klass = get_post_meta( $post->ID, '_item' . $i, true );
if( !empty($klass) ) {
echo "<div class='$klass'></div>";
}
}
This works as long as you do not need the $fooX variables later on. If you need them, you would have to use either mentioned variable variables or an array to collect all the values.
you're thinking well at a while loop
You could use:
$counter = 1;
while ($counter< 100) // or whatever limit you have
{
$foo = get_post_meta( $post->ID, '_item' . $counter , true );
if (!empty($foo)){
echo ("<div class='$foo' . $counter .' ></div>");
}
$counter++;
}
If you copy this code you're probably get into some compiling errors because of the string concatenation.
Basically you need to concatenate "_item" string with your current $counter.
Here are some string concatenation examples.
Let me know if you have any questions.
