    Delete files from directory

    in PHP Coding Help

    Posted

    I changed the code you pm me to this

     

    <?PHP 

$folder = "../images/"; 
$handle = opendir($folder); 

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

#echo the files 
foreach ($files as $file) { 
    echo "-<a href=$folder$file><label title=file>$file</a></label>";
echo "-<a href=filedelete.php?file=$file>Delete</a><br />";
    echo '<img src="$file" alt="image" width="150" />';
} 
?>

    i tried to get a thumnail to display but it doesnt

    Delete files from directory

    Well, firstly, the parameter you pass is called file - with a small f. The file you try to unlink is called $File with a capital F. Also, did you retrieve that variable from the $_GET array?

     

    Try:

     

    <?php
unlink($_GET['file']);
?>

     

    I did a s you recommended and get the following error

    Warning: unlink(Object) [function.unlink]: No such file or directory in C:\Program Files\Apache Group\Apache2\htdocs\gcproperty\images\delete.php on line 2

    Thanks for trying man, looks like a lot of work.

    The code here below lists all my files.

    <?php
$folder = "../images/"; 
$handle = opendir($folder); 

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

#echo the files 
foreach ($files as $file) { 
    echo "<br />$file<a href=delete.php?file=$file> 'Delete'</a>"; 
} 
?>

     

    I will make some changes later in its appearance but the code does its thing.

     

    the code i need to sort out is the delete.php

    i'm a newbie to php but am getting a little drift of things.

    i tried this code but to no avail

     

    delete.php

    <?php
{unlink($File);}
?>

    I used the code off this site and replaced the one that im using above.

     

    <?php
$folder = "../images/"; 
$handle = opendir($folder); 

# Making an array containing the files in the current directory: 
while (false !== ($file = readdir($handle)))
{
    if ($file != '.' && $file != '..')
       $files[] = $file; 
} 
closedir($handle); 

#echo the files 
foreach ($files as $file) { 
    echo "<br />$file<a href=delete.php?$file=$file> 'Delete'</a>"; 
} 
?>

    This shows all the files in my folder.

     

    Then i changed the delete.php file with this code only

     

    <?php
{unlink($File);}
?>

     

    and i get this error

     

    Warning: unlink() [function.unlink]: Permission denied in C:\Program Files\Apache Group\Apache2\htdocs\gcproperty\admin\delete.php on line 2

    I found a simpler code that does the same thing.

    Can i use this code with some extra coding to show the selected image and then option to delete on submit?

    It seems that there is a demand for this code.

    <?php
echo "<select name=\"file\">\n";
foreach (new DirectoryIterator('.') as $file) {
   // if the file is not this file, and does not start with a '.' or '..',
   // then store it for later display
   if ( (!$file->isDot()) && ($file->getFilename() != basename($_SERVER['PHP_SELF'])) ) {
      echo "<option>";
      // if the element is a directory add to the file name "(Dir)"
      echo ($file->isDir()) ? "(Dir) ".$file->getFilename() : $file->getFilename();
      echo "</option>\n";
   }
}
echo "</select>\n";
?>

    I wanted to create a file that lists all the files in a directory, show a thumbnail of each and give an option to delete.

    Is this hard to do?

    I have this code i found on the web

    <?php
// open the current directory
$dhandle = opendir('.');
// define an array to hold the files
$files = array();

if ($dhandle) {
   // loop through all of the files
   while (false !== ($fname = readdir($dhandle))) {
      // if the file is not this file, and does not start with a '.' or '..',
      // then store it for later display
      if (($fname != '.') && ($fname != '..') &&
          ($fname != basename($_SERVER['PHP_SELF']))) {
          // store the filename
          $files[] = (is_dir( "./$fname" )) ? "(Dir) {$fname}" : $fname;
      }
   }
   // close the directory
   closedir($dhandle);
}

echo "<select name=\"file\">\n";
// Now loop through the files, echoing out a new select option for each one
foreach( $files as $fname )
{
   echo "<option>{$fname}</option>\n";
}
echo "</select>\n";
?>

    It creates a nice list, but to get the files to display on click and an option to delete is over my head, any ideas or does someone have a code or link that could help mm.

    Thanks

    [SOLVED] Delete Record

    I got it to work ;D

    But this code looks wrong there are duplicate codes

     

    <?php
if ((isset($_POST['id'])) && ($_POST['id'] != "")) {
  $deleteSQL = sprintf("DELETE FROM employees WHERE id=%s",
                       GetSQLValueString($_POST['id'], "int"));

  mysql_select_db($database_gcproperty, $gcproperty);
  $Result1 = mysql_query($deleteSQL, $gcproperty) or die(mysql_error());

  $deleteGoTo = "property_deleted.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
    $deleteGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $deleteGoTo));
}

if ((isset($_POST['id'])) && ($_POST['id'] != "")) {
  $deleteSQL = sprintf("DELETE FROM employees WHERE id=%s",
                       GetSQLValueString($_POST['id'], "int"));

  mysql_select_db($database_gcproperty, $gcproperty);

$myFile = array();
for($i=1;$i<=9;$i++) {
$myFile[$i] = "../images/" . $_POST['photo' . $i];
     if (!empty($_POST['photo'.$i]))
          unlink($myFile[$i]);
}

  
}
  
  header("Location: $deleteGoTo");

}

mysql_select_db($database_gcproperty, $gcproperty);
$query_Recordset1 = "SELECT * FROM employees ORDER BY id ASC";
$Recordset1 = mysql_query($query_Recordset1, $gcproperty) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);

    I deleted the duplicated code but i get errors.

    [SOLVED] Delete Record

    in MySQL Help

    Posted

    I have records in my database that all have a id number that is unique ,

    But if i have the same name on a record and i delete the record from a dreamweaver generated code it deletes all records of the same name. I want to filter my deletion by id so that if i had 10 properties with the same name it would only delete the selected record?

    Does this make sense.

     

    Heres the code i use in my file

    <?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}

if ((isset($_POST['id'])) && ($_POST['id'] != "")) {
  $deleteSQL = sprintf("DELETE FROM employees WHERE id=%s",
                       GetSQLValueString($_POST['id'], "int"));

  mysql_select_db($database_gcproperty, $gcproperty);
  $Result1 = mysql_query($deleteSQL, $gcproperty) or die(mysql_error());

  $deleteGoTo = "property_deleted.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";
    $deleteGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $deleteGoTo));
}

if ((isset($_POST['name'])) && ($_POST['name'] != "")) {
  $deleteSQL = sprintf("DELETE FROM employees WHERE name=%s",
                       GetSQLValueString($_POST['name'], "text"));

  mysql_select_db($database_gcproperty, $gcproperty);
  $Result1 = mysql_query($deleteSQL, $gcproperty) or die(mysql_error());


$deleteGoTo = "property_deleted.php";
   if (isset($_SERVER['QUERY_STRING'])) {
    $deleteGoTo .= (strpos($deleteGoTo, '?')) ? "&" : "?";

          unlink($myFile[$i]);
}

  
}
  
  header("Location: $deleteGoTo");

}

mysql_select_db($database_gcproperty, $gcproperty);
$query_Recordset1 = "SELECT * FROM employees ORDER BY id ASC";
$Recordset1 = mysql_query($query_Recordset1, $gcproperty) or die(mysql_error());
$row_Recordset1 = mysql_fetch_assoc($Recordset1);
$totalRows_Recordset1 = mysql_num_rows($Recordset1);

    [SOLVED] Filter recordset by rank number

    in MySQL Help

    Posted

    I have a field in my table called rank, when a property is added my client chooses from a list a number from one to 10.

    and that number is inserted in the record, i thought this would be the best way to display the properties in order of rank.

    I am making this site in dreamweaver and am unsure on how to filter my recordset to display the results by rank, 1 being the best.

    Sorry for asking a stupid question, but am ;) learning

    [SOLVED] Auto_increment

    in MySQL Help

    Posted

    I changed it all so that there is no reference to (id) anywhere in my code.

    And changed my insert statement to

     

    mysql_query("INSERT INTO `employees` VALUES ('id','$name', '$rank', '$suburb', '$price', '$content', '$content2','$agentmobile', '$agentemail','$uploadFile0','$uploadFile1', '$uploadFile2', '$uploadFile3', '$uploadFile4', '$uploadFile5', '$uploadFile6', '$uploadFile7', '$uploadFile8')");

     

    And it does nothing.

    It says property added successfully but doesnt add the record ??? i removed the $ from the start of id.

    What am i doing wrong?

    Is my id field correctly structured, should it have a defult value? and should it be asigned as a primary key?

     

    Thanks in advanced

    ok, i get a drift of what u are saying, i deleted the input field and the get from form $id

     

    But in the insert statement it is formatted as

     

    <?php
//Writes the information to the database
      mysql_query("INSERT INTO `employees` VALUES ('$id','$name', '$rank', '$suburb', '$price', '$content', '$content2','$agentmobile', '$agentemail','$uploadFile0','$uploadFile1', '$uploadFile2', '$uploadFile3', '$uploadFile4', '$uploadFile5', '$uploadFile6', '$uploadFile7', '$uploadFile8')");

// ?>

    Should it be a different insert statement as $id now no longer exists in my files?

    Should it read

     

     

      mysql_query("INSERT INTO `employees` VALUES ('id','$name', '$rank', '$suburb', '$price', '$content', '$content2','$agentmobile', '$agentemail','$uploadFile0','$uploadFile1', '$uploadFile2', '$uploadFile3', '$uploadFile4', '$uploadFile5', '$uploadFile6', '$uploadFile7', '$uploadFile8')");

    So do i still need a hidden (id) field?

    and do i need the id in my proccess file?

     

    <?php
//This gets all the other information from the form 
$id=$_POST['id']; // do i need this?/////////////////////////////////////////////////////////////
$name=$_POST['name']; 
$rank=$_POST['rank']; 
$suburb=$_POST['suburb']; 
$price=$_POST['price']; 
$content=$_POST['content']; 
$content2=$_POST['content2']; 
$agentmobile=$_POST['agentmobile']; 
$agentemail=$_POST['agentemail']; 
$uploadFile0=($_FILES['uploadFile0']['name']); 
$uploadFile1=($_FILES['uploadFile1']['name']);
$uploadFile2=($_FILES['uploadFile2']['name']); 
$uploadFile3=($_FILES['uploadFile3']['name']);
$uploadFile4=($_FILES['uploadFile4']['name']);
$uploadFile5=($_FILES['uploadFile5']['name']);
$uploadFile6=($_FILES['uploadFile6']['name']);
$uploadFile7=($_FILES['uploadFile7']['name']);
$uploadFile8=($_FILES['uploadFile8']['name']);
?>

     

    Do i just do the code for the auto increment in this part of my code?

     

    //Writes the information to the database

     

     

    mysql_query("INSERT INTO `employees` VALUES ('$id','$name', '$rank', '$suburb', '$price', '$content', '$content2','$agentmobile', '$agentemail','$uploadFile0','$uploadFile1', '$uploadFile2', '$uploadFile3', '$uploadFile4', '$uploadFile5', '$uploadFile6', '$uploadFile7', '$uploadFile8')");

     

    //

     

    Sorry im stil learning, this is my first php/mysql project, thanks for your help ;)

     

    Is my id field setup correctly?

    Should it be a "primary key"

    It has a key beside it in dreamweaver and says that it is required?

     

    [SOLVED] Auto_increment

    in MySQL Help

    Posted

    Hi everyone.

    I have made a code that adds properties to a website, it uploads images, and inserts all the data(property details and image paths) to my database.

    It works well except for one thing, i cant get the auto_increment to work.

    I had the auto_increment field as "hidden" in my add_property.php file and it wouldnt work.

    If i had the field not hidden and added a number it works, and if that number is the same as as a other property id it replaces it.

    Do i need that field in my file at all? and should i even have it in my insert statement?

    Shouldnt that insert automatically my id in an auto increment.

    I am unable also to set a default value in my id field.

    here is my table structure.

     

    # Table structure for table `employees`

    #

     

    DROP TABLE IF EXISTS `employees`;

    CREATE TABLE `employees` (

      `id` int(4) NOT NULL auto_increment,

      `name` varchar(100) default NULL,

      `rank` int(10) default NULL,

      `suburb` varchar(100) default NULL,

      `price` varchar(100) default NULL,

      `content` text,

      `content2` text,

      `agentmobile` varchar(100) default NULL,

      `agentemail` varchar(100) default NULL,

      `photo1` varchar(100) default NULL,

      `photo2` varchar(100) default NULL,

      `photo3` varchar(100) default NULL,

      `photo4` varchar(100) default NULL,

      `photo5` varchar(100) default NULL,

      `photo6` varchar(100) default NULL,

      `photo7` varchar(100) default NULL,

      `photo8` varchar(100) default NULL,

      `photo9` varchar(100) default NULL,

      PRIMARY KEY  (`id`)

    ) ENGINE=MyISAM AUTO_INCREMENT=80 DEFAULT CHARSET=latin1 AUTO_INCREMENT=80 ;

     

    #

    This is my add_property code.

    <input name="id" type="text" id="id" size="3" />

     

    and this is my proccess file code

     

    <?php
if (!isset($_SESSION)) {
  session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";
