explode() expects parameter 2 to be string, array given

[tonyarnold]

Hi Nick, I hit this error tonight updating an older site:

explode() expects parameter 2 to be string, array given
/Users/tonyarnold/Sites/tonyarnold.com/extensions/search_index/data-sources/data.search.php line 94

89          } else {
90              $param_sections = array();
91          }
92          
93          $sections = array();
94          foreach(array_map('trim', explode(',', $param_sections)) as $handle) {
95              $section = Symphony::Database()->fetchRow(0,
96                  sprintf(
97                      "SELECT `id`, `name` FROM `tbl_sections` WHERE handle = '%s' LIMIT 1",
98                      Symphony::Database()->cleanValue($handle)

That might be the problem, how old? Search Index changed quite a lot during its development so the config array and table structure may not always be backwards compatible. Could you paste what you've got in yer config.php please?

Sure thing — it's never had search-index installed before today — it was an S2.1 install (which I've spent the evening upgrading to 2.2.1):

Hrm, am not aware of any Sympho changes that might be troublesome. So looks like $param_sections is probably null at this point. Are you passing ?sections=foobar on your URL?

[tonyarnold]

I was not, and that was indeed the problem. Close this issue as RTFM :)

Was my fault. When you're not passing sections I was defaulting the variable to an array, which explode chokes on. Now defaults to a string in 0.8.3. Cheers tarnold.
