我想查看“ $ name”变量中的内容,该怎么办?
add_action("wpcf7_before_send_mail", "wpcf7_do_something_else");
function wpcf7_do_something_else( &$WPCF7_ContactForm ) {
$name = $WPCF7_ContactForm->posted_data['your-name'];
var_dump($name);
}
答案 0 :(得分:0)
CF7使用AJAX提交表单,您无法以普通方式看到var_dump()
。因此,通过PHP,您可以使用WordPress debug.log文件。在“ wp-config.php”旁边而不是define('WP_DEBUG', false);
编写:
// Enable WP_DEBUG mode
define( 'WP_DEBUG', true );
// Enable Debug logging to the /wp-content/debug.log file
define( 'WP_DEBUG_LOG', true );
// Disable display of errors and warnings
define( 'WP_DEBUG_DISPLAY', false );
@ini_set( 'display_errors', 0 );
然后:
add_action("wpcf7_before_send_mail", "wpcf7_do_something_else");
function wpcf7_do_something_else( &$WPCF7_ContactForm ) {
$name = $WPCF7_ContactForm->posted_data['your-name'];
ob_start(); // start buffer capture
var_dump($name);
$contents = ob_get_contents(); // put the buffer into a variable
ob_end_clean(); // end capture
error_log($contents); // write the log file
}
作为选项,您可以使用JS通过CF7 DOM events在前端进行操作
示例-提交表单时:
<script>
document.addEventListener( 'wpcf7submit', function( event ) {
var inputs = event.detail.inputs;
for ( var i = 0; i < inputs.length; i++ ) {
if ( 'your-name' == inputs[i].name ) {
alert( inputs[i].value );
/*
or in console:
console.log( inputs[i].value );
*/
break;
}
}
}, false );
</script>
