DOes anyone know how to check for the value of an empty extrafield when the type is a link?

It seems to output : <a href="http://"></a>

when 'empty' but i cant seem to get a check for the presence of a link.

 

Dumping it out shows an empty string when the title is empty but its not really empty - it has a value of "<a href="http://"></a>" which for some reason I cant catch.

 

any ideas?

the value in the jos_k2_items table  field - extra_fields when entered and saved empty is:

[{"id":"2","value":["","http:\/\/","same"]}]

with a value it looks like

[{"id":"2","value":["xlinktext","http:\/\/test.com","same"]}]

I would test for \/\/" in the value string to test it (  \ / \ / "  ) using stripos

Use strip_tags before testing if the field is empty.

$field = strip_tags(get the field info here);

Then test if $field is empty.

 

Top tips guys thanks.

Its interesting that dump of variable only shows link text value and nothing else. Is this a php /json thing?

 

I like the strip_tags approach but saw it after I found a way. IN the end I checked for strlen > 23 becuase the default value has 23 characters when there is no link, even if php var_dump doesnt think so.

 

thanks alot for your replies
