如何通过PHP代码段在WordPress中使用$ _get

Question

I'm using WordPress and a plugin named "PHP snippets" to add my own coding in a WordPress page.

So, here is my code that I have added:

<script>
jQuery(document).ready(function(){
    showjob();
});
    function showjob() {    
    var intrest=document.getElementById("intrest").value; 
        jQuery.ajax({
            method: 'GET',
            url: 'jobsloader.php',
            data: {
                intrest: intrest,
              <?php 
                 if ($_GET['type']=="need") //the problem starts here... No matter what is the value of type in url it is always echoing feed... even if there is no type in url it is echoing feed...
                 {
                   echo "type: 'need'";
                 }
                 else
                 {
                   echo "type: 'feed'";
                 }
              ?>
            },
            success: function(data) 
            {
                document.getElementById("addcontainer").innerHTML = data;
            }
        });
    }
</script>

What am I doing wrong?

if you want more details, please ask in comments!

example: URL I was using was like this ' http://www.abcd.in/bs/?type=need '

moreover I want 3 cases:

1. if there is type

2. if type=need

3. if type=feed

Answer 1

嗯，我不知道你的插件，但在用GET请求来传递数据正确的方法是： http://www.abcd.in/bs.php?type=need或者实现URL重写，然后： http://www.abcd.in/bs/need

Answer 2

Wordpress supresses GET variables for security purposes, so you must register them in either a plugin or your theme's functions.php file :

function custom_query_vars_filter($vars) {
 $vars[] .= 'need';
 $vars[] .= 'feed';
 return $vars;
}
add_filter( 'query_vars', 'custom_query_vars_filter' );
