[英]Modal Pop Up not saving to db when button inside is clicked
I am new with jquery and ajax, so please be patient. 我是jquery和ajax的新手,所以请耐心等待。 I have this link:
我有这个链接:
<a href="#message" style="text-decoration:none" class="common2 simple3" >Message</a>
that shows this pop up when clicked: 单击时显示此弹出窗口:
<div id="message" class="modalDialog">
<div>
<h3>Create A Message</h3>
<form id="msgForm" name="msgForm" action="#" method="post">
<textarea id = 'msgContent' cols="48" rows="10" ></textarea>
<br>
<div id="create_btn">
<a href='' id = 'send' class="common simple2" style='margin-left:50px;text-decoration: none;'>Send</a>
</div>
<div id="cancel_btn">
<a href="#close" class="common simple2" style='margin-left:40px;text-decoration: none;'>cancel</a>
</div>
</form>
</div>
</div>
when I entered text in the textarea and show its content by alert(msgContent) in the script below, it shows 当我在文本区域中输入文本并在下面的脚本中通过alert(msgContent)显示其内容时,它将显示
$(document).ready(function()
{
$("#send").click(function(e)
{
e.preventDefault();
var msgContent = $("#msgContent").val();
alert(msgContent);
$.ajax({
url: 'message.php?message='+ msgContent,
type: 'GET',
dataType: 'json',
context: this,
success: function(result)
{
//if (result == true)
$(this).html('Send');
}
});
})
})
but when I try to pass it to a php page through ajax, it won't pass. 但是,当我尝试通过ajax将其传递到php页面时,它不会传递。 What could be wrong?
有什么事吗
this is message.php 这是message.php
$message = $_POST['message'];
$result = false;
$sql="INSERT INTO MESSAGE_LOG (sender,recepient, message)
VALUES($viewer,$viewed,$message)";
if (!mysqli_query($connection,$sql))
{
die('Error: ' . mysqli_error($connection));
}
You need to read the value from $_GET
: 您需要从
$_GET
读取值:
$message = $_GET['message'];
Or use the post method, with data attribute: 或使用具有data属性的post方法:
$(document).ready(function()
{
$("#send").click(function(e)
{
e.preventDefault();
var msgContent = $("#msgContent").val();
alert(msgContent);
$.ajax({
url: 'subscribe.php',
type: 'POST',
data: {message: msgContent},
//dataType: 'json', from your php I don't that that you are looking for json response...
context: this,
success: function(result)
{
//if (result == true)
$(this).html('Send');
}
});
})
})
Your JS should be this: 您的JS应该是这样的:
$(document).ready(function() {
$("#send").click(function(e) {
e.preventDefault();
var msgContent = $("#msgContent").val();
$.ajax({
url: 'message.php',
type: 'POST',
dataType: 'json',
data: {message: msgContent},
context: this,
success: function(result) {
alert('Message has been sent');
}
});
});
});
And your PHP this: 而你的PHP:
$message = $_POST['message'];
$result = false;
$sql="INSERT INTO MESSAGE_LOG (sender,recepient, message)
VALUES($viewer,$viewed,'$message')";
if (!mysqli_query($connection,$sql)) {
die('Error: ' . mysqli_error($connection));
}
