在企图通过css隐藏掉wordpress个人资料中的first-name 和 last-name时候,
在这里找到了相关的参考代码:
https://noexceptions.io/disabling-first-and-last-name-changes-in-the-wordpress-profile/
// Function to disable the first name and last name fields
function disable_first_and_last_name_fields() {
?>
<script type="text/javascript">
$(function() {
// Disable the first and last names in the admin profile so that user‘s cannot edit these
$(‘#first_name‘).prop( ‘disabled‘, true );
$(‘#last_name‘).prop( ‘disabled‘, true );
});
</script>
<?php
}
// Action hook to inject the generated JavaScript into admin pages
add_action( ‘admin_head‘, ‘disable_first_and_last_name_fields‘ );
比较简单,就是通过wordpress提供的action钩子,在内容管理页面注入jQuery脚本,把相关dom节点移除。
但是,直接在function.php中贴入的时候,发现并不起作用。
通过alert和console调试,发现代码块并未执行。
// Function to disable the first name and last name fields
function disable_first_and_last_name_fields() {
?>
<script type="text/javascript">
$(function() {
console.log("smt to be console");
alert("alert smt");
// Disable the first and last names in the admin profile so that user‘s cannot edit these
$(‘#first_name‘).prop( ‘display‘, false );
$(‘#last_name‘).prop( ‘disabled‘, true );
});
</script>
<?php
}
// Action hook to inject the generated JavaScript into admin pages
add_action( ‘admin_head‘, ‘disable_first_and_last_name_fields‘ );
最后在*上找到了该问题的原因:

就是把代码段中的$
换作jQuery
即可。
var $ = jQuery;
// Function to disable the first name and last name fields
function disable_first_and_last_name_fields() {
?>
<script type="text/javascript">
let $ = jQuery;
$(function() {
console.log("smt to be console");
alert("alert smt");
// Disable the first and last names in the admin profile so that user‘s cannot edit these
$(‘#first_name‘).prop( ‘display‘, false );
$(‘#last_name‘).prop( ‘disabled‘, true );
});
</script>
<?php
}
// Action hook to inject the generated JavaScript into admin pages
add_action( ‘admin_head‘, ‘disable_first_and_last_name_fields‘ );
It works !
