SELECT all from specific table and handle foreach row - php

Question

I stuck in some code here E.G:
Database table :
IMG_ID|IMG_SRC|EXPIRES|ACTION
------------------------------
4 | st.jpg |12546564| temp
So i try to delete the image from DB and from directory path so far i got this :
function removeTempPic(){
$uploadsDirectory1 = $_SERVER['DOCUMENT_ROOT'].'test/uploads/temp/';
//remove after 10 minute if unused
$timeout = time()-TEMPIC_TIMEOUT*60;
$q = "SELECT * FROM picsmanager WHERE expires < $timeout AND action=temp";
mysql_query($q, $this->connection);
foreach ($row = mysql_fetch_array($q)) {
$q = "delete * from picsmanager where=??"
//#unlink($uploadsDirectory1.$uploadFilename);
}
}
So what i try to do is select all from database table , and where timeout expire in some row delete each image from db and from directory
But this wont work because i dont know how to make it properly , Thanks.

Answer 1

you have multiple errors, in PHP and SQL
// enclose the string "temp" in single quotes
$q = "SELECT * FROM picsmanager WHERE expires < $timeout AND action='temp'";
$result = mysql_query($q, $this->connection);
// you need the result, not $q again
while($row = mysql_fetch_array($result)){
// run a new query to delete the extracted image
mysql_query("delete from picsmanager where IMG_ID=" . $row['IMG_ID'] . " LIMIT 1", $this->connection);
// delete the corresponding file
unlink($uploadsDirectory1.$row['IMG_SRC']);
}
Also, don't use the mysql_* functions anymore, they are becoming deprecated and will be removed from PHP in the future. Your code will stop working then. Learn how to use mysqli_* or PDO objects.

function removeTempPic(){
$uploadsDirectory1 = $_SERVER['DOCUMENT_ROOT'].'test/uploads/temp/';
//remove after 10 minute if unused
$timeout = time()-TEMPIC_TIMEOUT*60;
$q = "SELECT * FROM picsmanager WHERE expires < $timeout AND action='temp'";
mysql_query($q, $this->connection);
foreach($row = mysql_fetch_array($q)){
$q = sprintf("delete * from picsmanager where IMG_ID = %d", (int)$row['IMG_ID']);
//#unlink($uploadsDirectory1.$uploadFilename);
}
}
