我正在创建一个wordpress插件,我想将一个单选按钮值保存到wordpress数据库中,以便以后在另一个函数中使用它。但我不知道怎么做。我尝试了会话,但会话过期时此值将丢失。你能告诉我怎么做吗?
这是我的代码:
function e_option_page() { ?>
<form action="" id="testimonialsform" method="post">
<input type="radio" name="Option" value="Option 1">Option 1
<input type="radio" name="Option" value="Option 2">Option 2
<input type="radio" name="Option" value="Option 3">Option 3
<input type="submit" name="submit" value="Submit" />
</form>
<?php
if (isset($_POST['submit'])) {
if(isset($_POST['Option'])){
echo "You have selected :".$_POST['Option']; // Displaying Selected Value
}//End isset
}//End isset
}//End function
function e_setting_page() {
add_submenu_page('edit.php?post_type=testimonials', 'Settings', 'Settings', 'edit_posts', "settings",'e_option_page');
}
add_action('admin_menu' , 'e_setting_page');
最佳答案
您可以将任何选项值保存在“wp_usermeta”表中。
if (isset($_POST['submit'])) {
if(isset($_POST['Option'])){
//echo "You have selected :".$_POST['Option']; // Displaying Selected Value
// Save data
global $wpdb;
$table = $wpdb->prefix.'usermeta';
$data = array('meta_key' => 'your_option_name', 'meta_value' => $_POST['Option']);
$format = array('%s','%s');
$wpdb->insert($table,$data,$format);
$my_id = $wpdb->insert_id;
print_r($my_id);
}//End isset
}//End isset
之后,可以使用此选项选择值。
现在您可以检查选项值。
// So check and make sure the stored value matches $new_value.
if ( $new_value = get_user_meta( $user_id=0, 'your_option_name', true ) ) {
echo $new_value;
}else{
wp_die( __( 'An error occurred', 'textdomain' ) );
}
也可以更新元密钥
// Will return false if the previous value is the same as $new_value.
$updated = update_user_meta( $user_id=0, 'your_option_name', 'new_value' );
