How to create SEF URL’s in WordPress
While working on one of my client’s plugin I needed to provide search engine friendly url’s for some custom functionality that was needed and existing plugin was not supporting such urls
www.example.com/?param1=var1¶m2=var2¶m3=var3
but for search engine freindly url’s I want it to be like
www.example.com/var1/var2/var3
So here I am sharing small code snippet which works perfectly for my plguin and showing nice url’s.
We need to update the theme function.php file, just add the below code in function.php file and modify variables according to your need.
<?php
add_filter('rewrite_rules_array','wp_insertRewriteRules'); add_filter('query_vars','wp_insertQueryVars'); add_filter('init','flushRules'); // Remember to flush_rules() when adding rules function flushRules() { global $wp_rewrite; $wp_rewrite->flush_rules(); } // Adding a new rule function wp_insertRewriteRules($rules) { $newrules = array(); $newrules['(mytestpage)/([a-zA-Z0-9_-]*)/([a-zA-Z0-9_-]*)$'] = 'index.php?pagename=$matches[1]&var1=$matches[2]&var2=$matches[3]'; $allrules = $newrules + $rules; return $allrules; } // Adding the variables so that WP recognizes it function wp_insertQueryVars($vars) { array_push($vars, 'id'); array_push($vars, 'var1'); array_push($vars, 'var2'); return $vars; } ?>
To access these variables from plugin file use following code:
$var1 = $wp_query->query_vars['var1']; $var2 = $wp_query->query_vars['var2'];
Now this will solve your plugins search engine friendly issues.
