php - Query column for multiple values -

-

i have table looks 1 below, , doing search query multiple fields refine search job. @ moment able enter multiple fields, however, search results query entire database, not 1 specific id.

table:

    contentid   meta_key        meta_value       1   1       vacancytype     hospitality        2   1       vacancyrole     chef            3   1       vacancydate     2014-01-01          4   2       vacancytype     adin        5   2       vacancyarea     st albans            6   2       vacancydate     2014-01-01

code:

    $getjobs1 = "select distinct *                   cms_contentextra, cms_content                  cms_contentextra.meta_value  in ('$type','$key')                   , cms_content.contentid = cms_contentextra.contentid                  group cms_content.contentid";              $getjobs2 = mysql_query($getjobs1) or die("didn't query");           while ($getjobs3 = mysql_fetch_array($getjobs2)) {               echo ' - ' . $getjobs3[meta_value] . ' - ' . ' - ' . $getjobs3[contentid];           }

this return:

- st albans - - 8435 - st albans - - 8436 - hospitality & catering - - 8437 - st albans - - 8440 - hospitality & catering - - 8444 - hospitality & catering - - 8450 - hospitality & catering - - 8451 - st albans - - 8453

however, want show results have both area , type, , disregard others. @ moment seems displaying type , displaying area separately, unable show type in specific area.

i using 2 tables compare contentid more data stored in different table.

the in operand use or operation.

try use like such as:

where cms_contentextra.meta_value "%$type%$key%" or cms_contentextra.meta_value "%$key%$type%"
