Question

i am uploading some data to the db that contain title, news date and image, but when i want to update it i am facing problems.what i want to do basically if i update all the row except image then updation do not take place. what i want basically when i have to update lets suppose title only then it should update it but all other data should remain same but problem is that i have to select image again from my pc in updation. my scenario is that i just save the name in db not the whole path and hard code the path where ever i need to display the image

here is html

 <div class="row">
                            <label>Image upload</label>
                            <div class="right"><input type="file" name="file" value="<?php echo $row['images'];?>" /></div>
                        </div>

here is php

   if(($_GET['mod']=='edit') && (isset($_POST['hidden'])))
{




    echo $_FILES["file"]["name"];
        $allowedExts = array("jpg", "jpeg", "gif", "png");
        $extension = end(explode(".", $images));
        if ((($_FILES["file"]["type"] == "image/gif")
        || ($_FILES["file"]["type"]   == "image/jpeg")
        || ($_FILES["file"]["type"]   == "image/png")
        || ($_FILES["file"]["type"]   == "image/pjpeg"))

        && in_array($extension, $allowedExts))
          {
           if ($_FILES["file"]["error"] > 0)
            {

            echo $_FILES["file"]["error"] . "<br>";
            }
          else
            {
            move_uploaded_file($_FILES["file"]["tmp_name"], "upload-images/" . $images);
            $update="UPDATE headline SET 
                                                headline_title  = '$title',   
                                                headline_des    = '$description',   
                                                month           = '$month_name', 
                                                day             = '$day_name', 
                                                year            = '$year_name', 
                                                featured        = '$featured',
                                                headline        = '$headline',
                                                images          = '$images' 
                                                where id        = ".$_GET['id']."";
             $result = mysql_query($update);    

              }
            }

Answer 1

Submitting the form again will cause the new value of the file input which will be empty
so you have to check if it’s empty or not and act according to the status

For example

if($_FILES['file']['name'] != "")
{
      //upload the image with what ever you want 
      //move_uploaded_file($_FILES['file']['tmp_name'],$target.$image );
      //the SQL query should contain the updating the image column 
         if(($_GET['mod']=='edit') && (isset($_POST['hidden'])))
         {




echo $_FILES["file"]["name"];
    $allowedExts = array("jpg", "jpeg", "gif", "png");
    $extension = end(explode(".", $images));
    if ((($_FILES["file"]["type"] == "image/gif")
    || ($_FILES["file"]["type"]   == "image/jpeg")
    || ($_FILES["file"]["type"]   == "image/png")
    || ($_FILES["file"]["type"]   == "image/pjpeg"))

    && in_array($extension, $allowedExts))
      {
       if ($_FILES["file"]["error"] > 0)
        {

        echo $_FILES["file"]["error"] . "<br>";
        }
      else
        {
        move_uploaded_file($_FILES["file"]["tmp_name"], "upload-images/" . $images);
        $update="UPDATE headline SET 
                                            headline_title  = '$title',   
                                            headline_des    = '$description',   
                                            month           = '$month_name', 
                                            day             = '$day_name', 
                                            year            = '$year_name', 
                                            featured        = '$featured',
                                            headline        = '$headline',
                                            images          = '$images' 
                                            where id        = ".$_GET['id']."";
         $result = mysql_query($update);    

          }
        }
}
else
{
      //SQL update without image 
        $update="UPDATE headline SET 
                                            headline_title  = '$title',   
                                            headline_des    = '$description',   
                                            month           = '$month_name', 
                                            day             = '$day_name', 
                                            year            = '$year_name', 
                                            featured        = '$featured',
                                            headline        = '$headline'
                                            WHERE id        = ".$_GET['id']."";
         $result = mysql_query($update);    

}

if you don’t want the image to be edited simply you can remove it from the update and the form used for that or but it’s path in hidden input

Hope this will help

According to your comment the query should look something like this

        $update="UPDATE headline SET 
                                            headline_title  = '$title',   
                                            headline_des    = '$description',   
                                            month           = '$month_name', 
                                            day             = '$day_name', 
                                            year            = '$year_name', 
                                            featured        = '$featured',
                                            headline        = '$headline'
                                            WHERE id        = ".$_GET['id']."";
         $result = mysql_query($update);    

I think you need to use good intending to make your code more readable and maintainable in the future 🙂
