Examples

Example 1 <?php // Find can be called in one of three ways

// Example #1 $mypod = pods( 'mypod', $params );

// Example #2 $mypod = pods( 'mypod' )->find( $params );

// Example #3 $mypod = pods( 'mypod' ); $mypod->find( $params );

// Here's how to use find() $params = array( 'limit' => 3,
'page' => 2,
// Be sure to sanitize ANY strings going here 'where'=>"category.name = 'My Category'" );

// Run the find $mypod = pods( 'mypod', $params );

// Loop through the records returned while ( $mypod->fetch() ) { echo $mypod->display( 'name' ) . "\n"; } The above example will output: Pod Title 1 Pod Title 2 Pod Title 3 Using a variable in a where clause When the where clause must be created dynamically, a variable can be passed to it like in this example:

<?php // get value from input to a form $keyword = like_escape( pods_v_sanitized( 'keyword', 'post' ) );

// set up find parameters, where meta field title matches $keyword $params = array( 'where' => 't.post_title LIKE "%' . $keyword . '%" OR my_field.meta_value LIKE "%' . $keyword . '%"' );

//search in articles pod $pods = pods( 'articles', $params );

//loop through results if ( 0 < $pods->total() ) { while ( $pods->fetch() ) { echo $pods->display( 'issue' ); } } ?> Additional Information
