I have a profile page on which i want to show all posts with a the tag xy, that is specified in a custom field. I’m having trouble handing the String, which i got from the field over to the wp-query, which gives me the posts with the tag.
I have currently this to setup my query:
$original_query = $wp_query;
$tagstr = '' + the_field('usertag');
$wp_query = null;
$wp_query = new WP_Query( 'tag=$tagstr');
The akward thing is, that it outputs the String of the field itself onto the page sourcecode. I have no echo of the $tagstr variable and am not getting the value of the “usertag” field anywhere else on the page whatsoever, so i absolutely don’t know where this is coming from.
The funny thing is it works fine if i hardcode the String into my code like this:
$original_query = $wp_query;
$wp_query = null;
$wp_query = new WP_Query( 'tag=test');
I’m really confused about what is going wrong there…
Hi @flowbob,
That would be because the_field echoes the output.
You want to use get_field => http://www.advancedcustomfields.com/resources/functions/get_field/
I tried
$original_query = $wp_query;
$tagstr = get_field('usertag');
echo $tagstr;
$wp_query = null;
$wp_query = new WP_Query( 'tag=$tagstr')
but it does nothing. (i echo’d $tagstr to check whether it’s the right value and it seems to be correct).
If echo $tagstr; shows a value, then it sounds like tag=$tagstr is just returning zero results.
“Tag=” can only look for tag slugs. Are you sure that the value of $tagstr is equal to the tag slug?

Hi @flowbob
Becuase your WP_Query uses a literal string 'tag=$tagstr', the variable will not be converted.
If you wish to use the parameter in this manor, just cahnge to double quotes like so:
"tag=$tagstr"
You can also wrap variables like so:
"tag={$tagstr}"
Your best bet is to always use an array instead of a string. Also make sure you use the post_type param.
Thanks

@sdawson26 the tag was the right one the issue was the conversion of the string, as elliot pointed out.
@elliot this was exactly what solved the issue for me. thaks!
I should really try to lern PHP – at least the very basics like these datatypes…
I really appreciate the support you guys give here! It’s awesome.
And @elliot: the plugin and the page here is just plain awesome! Thanks!
