J'ai le code suivant où l'utilisateur entre les données et une fois qu'il clique sur le bouton de sauvegarde, la table affichée est rechargée où le nouvel enregistrement si inséré dans la base de données est affiché. La table lit les données de la base de données. et im en utilisant ajax pour charger les données et enregistrer l'enregistrement. voici mon code html:actualiser la table dans la page lorsque vous appuyez sur le bouton Enregistrer sans actualiser toute la page

$("#save").click(function(){
//receiving data entered by user from design.php
var name = $('#name').val();

$.ajax({
type:'POST',
url: 'contactData.php',
data:{"name":name,"telephone":telephone,"email":email, "username":username, "password":password},
// dataType:'json',
success: function(data) {
var result = JSON.parse(data);
$("#validate").html(result.msg);
}
});//end of ajax
});//end of listener
});//end of javascript
et mon code php est la suivante:
<?php
//connect to the database
$con=mysql_connect("localhost","root","");
mysql_select_db("mysql",$con) or die(mysql_error());
$notTaken=false;//variable to check if the username is taken or not
$username=$_POST["username"];
//to check if username is available in the database
$query = "SELECT username FROM users";
$result = mysql_query($query) or die(mysql_error());
//to check if it is the first record
$result2 = mysql_query("SELECT * FROM users", $con);
$num_rows = mysql_num_rows($result2);
if($num_rows==0)
{
//if there are still no records don't do anything for now, once out of the if will go to validty()
}
else{
while($row = mysql_fetch_array($result))
{
if($username == $row['username'])
{
$takenMsg='{"msg":"Username Taken"}' ;
echo $takenMsg;
$exitMSG='{"msg":"Try Another Username"}';
exit($exitMSG);
}
else{
$notTaken=true;
}
}
}
// after checking if the usernname exists or not check for field valdation
validity();
//check for valididty
function validity(){
//variables obtained by ajax
$name=$_POST["name"];
$telephone=$_POST["telephone"];
$email=$_POST["email"];
$username=$_POST["username"];
$password=$_POST["password"];
//check if phone is all digits
$pattern_phone = "|^[0-9\+][0-9\s+\-]*$|i";
//check if email is in the right form([email protected])
$pattern_email="/([\w\-]+\@[\w\-]+\.[\w\-]+)/";
//validate if fields are empty
if (($name == "") || ($email == "") || ($telephone == "") || ($username == "") || ($password == ""))
{
$errorMsg = '{"msg":"some input is missing"}';
echo $errorMsg;
}
//validate if email is in the right form
elseif (!preg_match($pattern_email, $email))
{
$errorMsg = '{"msg":"email format is incorrect"}';
echo $errorMsg;
}
//validtae if the telephone is all digits
elseif (!preg_match($pattern_phone, $telephone))
{
$errorMsg = '{"msg":"telephone should be all digits"}';
echo $errorMsg;
}
//if all fields aquire the correct validation, insert record to database
else
{
$query1=mysql_query("INSERT INTO users(name,telephone,email,username,password) values('$name','$telephone','$email','$username','$password') ");
//if record inserted successfully display msg indicating so
if($query1)
{
$msg='{"msg":"Your info has been sent"}';
echo $msg;
}
//if record not inserted sucessfully display msg indicating so
else
{
$msg='{"msg":"Error in sending your info"}';
echo $msg;
}
}
}//end of function validity()
en appuyant sur le bouton Enregistrer si tous les champs sont corrects son enregistrement dans la base de données, mais l'enregistrement n'est pas montré à la fin de la table, je veux en cliquant sur la sauvegarde et l'enregistrement est sauvegardé dans la base de données le nouveau dossier sera également affiché
