Kāpēc uzspiežot "Create new topic" pogu, jquery izsūta divus pieprasījumus? Un datubāzē parādas 2 vienādi ieraksti? Ir kādas iespējas šo problēmu noverst?

 

javascript


$(document).ready(function(){
$('#topicForm').submit(function(e) {
submitNewTopic();
e.preventDefault();
});
});

function submitNewTopic(){
hideshow('loading',1);
error(0);
$.ajax({
type: "POST",
url: "/submitnewTOPIC.php",
data: $('#topicForm').serialize(),
dataType: "json",
success: function(msg){
if(parseInt(msg.status)==1){
$('#postT').html("Completed");
}else if(parseInt(msg.status)==0){
error(1,msg.txt);
}
hideshow('loading',0);
}
});
}

function hideshow(el,act){
if(act) $('#'+el).css('visibility','visible');
else $('#'+el).css('visibility','hidden');
}

function error(act,txt){
hideshow('error',act);
if(txt) $('#error').html(txt);
}

 

html

<div id="postT">
<form id="topicForm" method="post">
<textarea name="txt" id="txt" style="width:430px; height:150px"></textarea><br/>
<input type="submit" value="Create new topic">
</form>
</div>

 

submitnewTOPIC.php


function msg($status,$txt){
return '{"status":'.$status.',"txt":"'.$txt.'"}';
}

if(empty($_POST['txt'])){
die(msg(0,"You must complete all fields!"));
}

$createtopic = $DBH->prepare("INSERT INTO topics(`author`, `text`, `when`) VALUES(:author, :text, :when)");
$createtopic->execute(array(":author"=>$userID, ":text"=>$_POST['txt'], ":when"=>time()));
echo msg(1,"_");
