A variable as array value

[jarvis]

Hi All,

I think I'm being pretty daft!

 

I currently have the following:

$categories = array( 'cat 1', 'cat 2', 'cat 3');

This is fine but the issue is it required someone manually entering the values.

 

I therefore setup a loop which gets all my categories:

$subcats = array();
foreach($wctTerms as $wctTerm) {
	$subcats[] = $wctTerm->slug;
}

I can then use:

$comma_separated  = implode (", ", $subcats);

Which spits out what I need: cat 1, cat 2, cat 3 etc.

 

But how do I get this back into the original $categories part. I thought:

$categories = array( $comma_separated  );

But that doesn't work

 

Feeling pretty daft right now! Any pointers much appreciated

I think you're looking for explode(). More information can be found here:

So, if I understand you, there is an array ($subcats) which you implode into a comma separated string and which you now want to put back into an array.

 

But you already have that array - $subcats

How about:

 

$categories = $wctTerms;

Thank you all for you comments

 

@Barand, I think that was the missing piece I needed. So if I've understood you correctly, I could just do this:

$categories = array();
foreach($wctTerms as $wctTerm) {
	$categories[] = $wctTerm->slug;
}

Would that work?

 

I think I've over complicated something very simple (the usual!)

That should work just fine. How often do you think you will need the imploded version of the categories in a single script? Depending on how often you need the value, you can just leave the categories as an array. Then just implode the values as needed.

I wish I knew what 'slug' was....

@ginerjm - its a wordpress/woocommerce term

@cyberRobot - if I go the route as per my code a minute ago, shouldnt this negate the need to use implode?

I have a feeling it's related to WordPress. The "wtc" part seems like it's connected to the Woocommerce plugin. More information about WordPress slugs can be found here:

That depends on what you are looking to do. If you don't need the categories/slugs as a string, you don't need to use implode.

I guess if the code above means i don't need to convert to a string, then put the string back into the array then I think we're all good

 

apologies if I've confused the matter

 

All I want to do is automate the process so instead of typing everything into $categories = array ('manually adding each category'); I thought if I loop the categories I can make this automatically happen

 

I've a feeling I got myself in a muddle and therefore, if I set up my loop and add each value into the $categories array, this will do the same as the line of code above?
