我有一个模态形式的表格:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Add user
</button>
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form action="" method="post" id="saveperson">
<label for="newcat">Project Name</label>
<input type="text" name="newcat" value="">
<label for="description">Description</label>
<input type="text" name="description" value="">
<input type="submit" name="user" value="Submit">
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
提交后,我运行js:
$(document).ready(function() {
$('#saveperson').submit(function(event) { //Trigger on form submit
var postForm = { //Fetch form data
'name' : $('input[name=newcat]').val(),
'desc' : $('input[name=description]').val() //Store name fields value
};
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'process.php',
data : postForm, //Forms name
dataType : 'json',
success : function(data) {
$('.modal-body').html("Done!");
}
else {
$('.modal-body').html("Error!");
}
}
});
event.preventDefault();
});
});
然后它应该在process.php中运行
<?php
header ( "Content-Type: application/json");
$cat_ID = get_cat_ID( sanitize_title_for_query($_POST['newcat']) );
// Check if category exists
if($cat_ID == 0) {
$cat_name = sanitize_text_field($_POST['newcat']);
$cat_desc = sanitize_text_field($_POST['description']);
$cat_slug = sanitize_title_with_dashes($cat_name);
$my_cat = array(
'cat_name' => $cat_name,
'category_description' => $cat_desc,
'category_nicename' => $cat_slug,
'category_parent' => 0
);
if( wp_insert_category( $my_cat ) ) {
// Category added successfully
die ( json_encode ( array ( "success" => 1)));
} else {
// Error while creating new category
die ( json_encode ( array ( "success" => 0)));
}
} else {
// That category already exists
die ( json_encode ( array ( "success" => 0)));
}
?>
但是在提交之后,什么也没有发生,并且数据没有保存在数据库中,这意味着无法正常工作。如果我在没有ajax的标准php中使用此php tho,它将起作用并将数据保存在db中
<?php
header ( "Content-Type: application/json");
if( isset( $_POST['user'] ) ) {
if( !empty( $_REQUEST['newcat'] ) ) {
$cat_ID = get_cat_ID( sanitize_title_for_query($_POST['newcat']) );
// Check if category exists
if($cat_ID == 0) {
$cat_name = sanitize_text_field($_POST['newcat']);
$cat_desc = sanitize_text_field($_POST['description']);
$cat_slug = sanitize_title_with_dashes($cat_name);
$my_cat = array(
'cat_name' => $cat_name,
'category_description' => $cat_desc,
'category_nicename' => $cat_slug,
'category_parent' => 0
);
wp_insert_category( $my_cat );
}
}
}
?>

浏览器控制台中存在错误:
$(document).ready(function() {
$('#saveperson').submit(function(event) { //Trigger on form submit
var postForm = { //Fetch form data
'name' : $('input[name=newcat]').val(),
'desc' : $('input[name=description]').val() //Store name fields value
};
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'process.php',
data : postForm, //Forms name
dataType : 'json',
success : function(data) {
$('.modal-body').html("Done!");
}
else {
$('.modal-body').html("Error!");
}
}
});
event.preventDefault();
});
});
注意
else {
$('.modal-body').html("Error!");
}
错误:
未捕获到的SyntaxError:其他意外令牌
删除else块,它应该可以工作
应该是:
$(document).ready(function() {
$('#saveperson').submit(function(event) { //Trigger on form submit
var postForm = { //Fetch form data
'name' : $('input[name=newcat]').val(),
'desc' : $('input[name=description]').val() //Store name fields value
};
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'process.php',
data : postForm, //Forms name
dataType : 'json',
success : function(data) {
$('.modal-body').html("Done!");
}
});
event.preventDefault();
});
});

您尝试过吗?
$( "#saveperson" ).submit(function( event ) {
let form = $( this );
let formData = new FormData(form[0]);
$.ajax({ //Process the form using $.ajax()
type : 'POST', //Method type
url : 'process.php',
data : formData,
success : function(data) {
$('.modal-body').html("Done!");
}
});
event.preventDefault();
});

问题是我正在从外部php文件运行wordpress标准功能,但无法正常工作。为了实现我正在做的事情,我不得不使用
function.php and wordpress ajax
add_action( 'wp_footer', 'ajax_Person' );
function ajax_Person() { ?>
<script type="text/javascript">
jQuery("#createCat").on("click", function(e){
e.preventDefault();
person();
});
function person(){
jQuery.ajax({
url: '<?php echo admin_url('admin-ajax.php'); ?>',
type: 'post',
data: { action: 'data_person', catName: jQuery('#newCat').val(), catDesc: jQuery('#descRiption').val() },
success: function(data) {
}
});
}
</script>
<?php }
add_action('wp_ajax_data_person' , 'data_person');
add_action('wp_ajax_nopriv_data_person','data_person');
function data_person(){
$catname = $_POST['catName'];
$catdesc = $_POST["catDesc"];
$cat_ID = get_cat_ID( sanitize_title_for_query($catname) );
// Check if category exists
if($cat_ID == 0) {
$cat_name = $catname;
$cat_desc = $catdesc;
$cat_slug = sanitize_title_with_dashes($cat_name);
$my_cat = array(
'cat_name' => $cat_name,
'category_description' => $cat_desc,
'category_nicename' => $cat_slug,
'category_parent' => 0
);
if( wp_insert_category( $my_cat ) ) {
echo 'Category added successfully';
} else {
echo 'Error while creating new category';
}
} else {
echo 'That category already exists';
}
}
