WordPress 通过 AJAX 将数据保存到数据库
WordPress save data to DB via AJAX
总的来说,我对 WordpPress 和 Web 开发还很陌生。
尝试通过 ajax 调用将数据从我在页面上的表单保存到 wordpress 数据库。
这是我的表格:
<form type="post" action="" id="MSRPForm">
<div class="py-3 my-0 form-group row border-top border-bottom align-items-center">
<label for="inputEmail" class="col-sm-4 col-form-label" >Email</label>
<div class="col-sm-8">
<input name="Email" type="text" class="form-control-plaintext" id="inputEmail"
placeholder="email@example.com">
</div>
</div>
<div class="py-3 my-0 form-group row border-top border-bottom align-items-center">
<label for="inputZipCode" class="col-sm-4 col-form-label" >Zip Code</label>
<div class="col-sm-8">
<input name="ZipCode" type="text" class="form-control" id="inputZipCode" placeholder="Enter your Zip Code">
</div>
</div>
<div class="py-3 my-0 form-group row border-top border-bottom align-items-center">
<label for="inputMSRP" class="col-sm-6 col-form-label font-weight-bold" >MSRP<br><small>Manufacturer's Suggested Retail Price</small></label>
<div class="col-sm-6">
<input name="MSRP" type="text" min="1000" class="form-control text-right" id="inputMSRP" placeholder="Enter the MSRP">
</div>
</div>
<button id="msrp-btn" type="button" class="btn btn-primary my-2">Calculate</button>
</form>
这是一个AJAX。它被包装到 jQuery 函数中,所以它确实有效:
let ajaxurl = "wp-admin/admin-ajax.php";
$(document).ready(function(){
$("#msrp-btn").click(function(e) {
e.preventDefault();
let email = $('#inputEmail').val();
let zipCode = $('#inputZipCode').val();
let msrp = $('#inputMSRP').val();
let info = {
'action': 'addMSRP',
'email': email,
'zipCode' : zipCode,
'msrp' : msrp
};
jQuery.ajax({
type: "POST",
url: ajaxurl,
data: info,
beforeSend: function() {
$('#myModal').modal('show');
// console.log( info);
},
success: function(res){
console.log(res);
},
error: function(res){
console.log(res)
},
});
});
});
最后这是我 functions.php
中的代码
add_action('wp_ajax_addMSRP', 'addMSRP');
add_action('wp_ajax_nopriv_addMSRP', 'addMSRP');
function addMSRP() {
global $wpdb;
$email = $_POST['Email'];
$zipCode = $_POST['ZipCode'];
$MSRP = $_POST['MSRP'];
if ( $wpdb->insert( 'msrp_info', array(
'email' => $email,
'zipCode' => $zipCode,
'MSRP' => $MSRP
) ) === false ) {
wp_die('Database Insertion failed');
} else {
echo "Info successfully added, row ID is ".$wpdb->insert_id;
}
exit();
}
当数据传递到服务器时,代码似乎可以正常工作,但它没有保存到数据库中。
如果有人能告诉我我做错了什么,将不胜感激。谢谢。
我发现有几个问题,即您没有将正确的变量传递给 $_POST。您还需要指定数据库的名称 table。尝试使用以下代码插入数据库。
add_action('wp_ajax_addMSRP', 'addMSRP');
add_action('wp_ajax_nopriv_addMSRP', 'addMSRP');
function addMSRP(){
global $wpdb;
//output will be your debug tool - if it posts it works.
$output = ['status' => 1];
$email = sanitize_text_field($_POST["email"]);
$zipcode = sanitize_text_field($_POST["zipCode"]);
$MSRP = sanitize_text_field($_POST["msrp"]);
$table = $wpdb->prefix . 'enteryourdatabasename';
//This below code has to match exactly what the database reads.
//If 'msrp' in the database the table is 'MsRp' - than replace it as spelled below.
$data = array(
'email' => $email,
'zipcode' => $zipcode,
'msrp' => $MSRP,
);
$wpdb->insert($table, $data);
//using wp_send_json to send that response and kill script.
$output['status'] = 2;
wp_send_json($output);
}
