我正在使用php和ajax一起从用户访问数据并将其插入到database.problem,它可以与小字符串一起正常工作,但是当我尝试在10000个字符上发送数据时,浏览器提示错误,提示url to long..
我可以在php中进行更改但是我希望它是动态的,所以我只能使用这种方式..帮助我。
function submitQuestion(){
var x=document.forms['Ask']['title'].value;
var y=document.forms['Ask']['description'].value;
if(x.length == 0 || y.length == 0){
alert('Insufficient Data');
}else{
startLoading();
console.log(y);
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function(){
if(this.readyState == 4 && this.status==200){
console.log(this.responseText);
if(this.responseText == "All Done"){
clearInterval(startLoadingClearInt);
alert("data Inserted");
// window.location.replace('../profile/userprofile.php');
}
}
};
//here x is very inn some cases and produces an error
xhttp.open("POST","./submitQuestion.php?title="+x+"&description="+y, true);
xhttp.send();
}
}
最佳答案
您不能通过url传输大数据(如messerbill所说)。您必须将它们发送到正文中:
function submitQuestion(){
var x=document.forms['Ask']['title'].value;
var y=document.forms['Ask']['description'].value;
if(x.length == 0 || y.length == 0){
alert('Insufficient Data');
}else{
startLoading();
console.log(y);
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function(){
if(this.readyState == 4 && this.status==200){
console.log(this.responseText);
if(this.responseText == "All Done"){
clearInterval(startLoadingClearInt);
alert("data Inserted");
// window.location.replace('../profile/userprofile.php');
}
}
};
//here x is very inn some cases and produces an error
xhttp.open("POST","./submitQuestion.php", true);
xhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xhttp.send("title="+x+"&description="+y");
}
}
在PHP脚本中,您可以通过$ _POST数组而不是通过$ _GET数组获取数据!
