我想从insert.php中选择streamitem_id并将其添加到我现有的post div中。我需要发布的帖子的ID,所以我可以将它添加到我的div中,所以稍后当我添加我的删除按钮时,它将删除帖子和保存它的div。希望我有道理,我可以用我正在努力学习的东西来做到这一点,但是当它刚开始时它就像任何一种语言一样困难。
AJAX
<script>
$(document).ready(function(){
$("form#myform").submit(function(event) {
event.preventDefault();
var content = $("#toid").val();
var newmsg = $("#newmsg").val();
$.ajax({
type: "POST",
url: "insert.php",
data: "toid=" + content + "&newmsg=" + newmsg,
success: function(){
$("#homestatusid").prepend("<div id='divider-"+WHERE MY STREAMITEM_ID NEEDS TO BE+"'><div class='userinfo'>"+newmsg+"</div></div>");
}
});
});
});
</script>
INSERT.PHP
$check = "SELECT streamitem_id FROM streamdata WHERE streamitem_id=$user1_id";
$check1 = mysql_query($check);
$check2 = mysql_num_rows($check1);
echo $check2;

在你的javascript中应该是
$.ajax({
type: "POST",
url: "insert.php",
data: {toid:content, newmsg: newmsg}, # pay attention to this line
success: function(data){
$("#homestatusid").prepend("<div id='divider-"+data+"'><div class='userinfo'>"+newmsg+"</div></div>");
}
});
PHP
$toid = isset($_POST['toid']) ? $_POST['toid'] : null;
$newmsg = isset($_POST['newmsg']) ? $_POST['newmsg'] : null;
不要使用mysql_*
,因为它已弃用

传递给success
回调的第一个参数是来自AJAX调用的responseText。将您的jQuery代码修改为:
success: function(responseText){
$("#homestatusid").prepend("<div id='divider-"+responseText+"'><div class='userinfo'>"+newmsg+"</div></div>");
// I'm assuming that insert.php returns just the ID you're interested in
}
