am facut o pagina in care userii sa intre sa stearga anunturile lor.
am facut asa:
pag_anunt_user.php

Cod: Selectaţi tot

<style type="text/css">
<!--
.style1 {font-weight: bold}
.style3 {

iar stergere.php

Cod: Selectaţi tot

<?php
include 'connect_to_mysql.php';
$id = $_POST['sterge'];
mysql_query("DELETE FROM anunturi WHERE id='" .$id. "'");

?>
dar e o problema la acest script pentru ca daca cineva vrea sa faca un rau la site face un formular cum am facut eu la pag_anunt_user.php si imi sterge ce anunturi vrea el.
cum pot sa fac o restrictie in pagina sterge.php care sa nu fie afisata daca anuntul pe care il sterge nu este al userului care vrea sa stearga
Sper ca m-ati inteles
Multumesc.

Daca la anunturi ai si numele celui care a postat, atunci poti sa faci un select dupa nume, sau daca il in sessiune e foarte bine. Cu acest nume faci un search in tabela cu anunturi dupa nume si id-ul din get:

WHERE postat_de = "NUME" AND id="ID"

aha...am inteles.fac asta in sterge.php ?
ceva de genu:

Cod: Selectaţi tot

<?php
include 'connect_to_mysql.php';
if (isset($_SESSION['username'])) {
$nume = $_SESSION['username'];
$id = $_POST['sterge'];
mysql_query("DELETE FROM anunturi WHERE nume='" .$nume. "' AND id='" .$id. "'");
}
else {echo "Anuntul nu iti apartine"}
?>
nu?

am facut asa:

Cod: Selectaţi tot

<?php
session_start();
include 'connect_to_mysql.php';
if (isset($_SESSION['username'])) {
$nume = $_SESSION['username'];
$id = $_POST['sterge'];
mysql_query("DELETE FROM anunturi WHERE nume='" .$nume. "' AND id='" .$id. "'");
}
else echo 'Anuntul nu va apartine';
?>
cred ca merge ca nu imi apare Anuntul nu va apartine si anuntul se sterge

Incearca asa:

Cod: Selectaţi tot

<?php
include 'connect_to_mysql.php';

$select = mysql_query("SELECT * FROM anunturi WHERE nume = '$nume' AND id = '$id'");
$randuri = mysql_num_rows($select);

if($randuri == 1){
$sterge = mysql_query("DELETE FROM anunturi WHERE nume='" .$nume. "' AND id='" .$id. "'");
}else{
echo "Cred ca vrei sa stergi ceva ce nu-i al tau!"
}
?>
Pune tu variabila cu sesiunea.

Eu zic ca merge cum am facut eu mai sus.
Cu al tau imi zice doar Cred ca vrei sa stergi ceva ce nu-i al tau!
Multumesc
