我正在尝试将一组表单参数发送到PHP脚本进行处理.
I am trying to send a group of form parameters over to a PHP script for processing.
我以前曾经使用$.post做过这样的事情,但是现在我试图通过使用$.ajax来严格完成它.
I've previously done something like this using $.post, but now I'm trying to get it done strictly by using $.ajax.
这是应该将所有变量发送到PHP脚本的jQuery click事件:
Here is the jQuery click event that is supposed to send all of the variables to the PHP script:
$('.searchSubmit').on('click', function() { var searchCriteria = { import_bill: $('#import_bill').val(), import_ramp: $('#import_ramp').val(), import_delivery: $('#import_delivery').val(), // few more form parameters }; $.ajax({ url: 'api/railmbs.php', // process script type: 'POST', data: searchCriteria, // parameter group above dataType: 'html' // had this set to json, but only got fail success: function(data, textStatus, jqXHR) { console.log(data); }, error: function(jqHHR, textStatus, errorThrown) { console.log('fail'); } }); });这是一个名为railmbs.php的PHP脚本:
Here is the PHP script, called railmbs.php:
<?php if(isset($_POST['searchCriteria'])) { $value = $_POST['searchCriteria']; $_SESSION['where'] = ""; $import_bill = mysqli_real_escape_string($dbc, trim($value['import_bill'])); $import_ramp = mysqli_real_escape_string($dbc, trim($value['import_ramp'])); $import_delivery = mysqli_real_escape_string($dbc, trim($value['import_delivery'])); echo $import_bill; // just trying to echo anything at this point } ?>不确定我在做什么错.如果在上述IF之前输入echo hello,则控制台将相应输出.但是我似乎无法从IF内部获得任何东西给echo.
Not sure what I am doing wrong. If I echo hello before the IF above, the console will output accordingly. But I cannot seem to get anything to echo from inside the IF.
有人看到我的错误吗?
推荐答案您没有设置"searchCriteria"变量.
You are not setting the "searchCriteria" variable.
更改此:
$('.searchSubmit').on('click', function() { var searchCriteria = { import_bill: $('#import_bill').val(), import_ramp: $('#import_ramp').val(), import_delivery: $('#import_delivery').val(), // few more form parameters }; $.ajax({ url: 'api/railmbs.php', // process script type: 'POST', data: searchCriteria, // parameter group above dataType: 'html' // had this set to json, but only got fail success: function(data, textStatus, jqXHR) { console.log(data); }, error: function(jqHHR, textStatus, errorThrown) { console.log('fail'); } }); });收件人:
$('.searchSubmit').on('click', function() { var data = { searchCriteria: { import_bill: $('#import_bill').val(), import_ramp: $('#import_ramp').val(), import_delivery: $('#import_delivery').val(), // few more form parameters } }; $.ajax({ url: 'api/railmbs.php', // process script type: 'POST', data: data, // parameter group above dataType: 'html' // had this set to json, but only got fail success: function(data, textStatus, jqXHR) { console.log(data); }, error: function(jqHHR, textStatus, errorThrown) { console.log('fail'); } });更多推荐
