Hello experts,

 

Please forgive me as this code is very long. I didn't want to miss providing the important you may need to assist.

 

On the code posted above, a user can upload up to 10 different pdf files to the server.

 

The filename associated with each uploaded file is saved to the database.

 

This is how the uploaded file can be related to the filename on the database.

 

This works fine.

 

Issue I am faced with is how to delete (unlink) the filename on the server.

 

I will like each file upload box to have the unlink bit next to it.

 

This way, the unlink is only is only visible when there is an uploaded file.

 

I have been struggling for days now trying to figure out where to add the markup next to each file.

 

Any assistance is greatly appreciated.

That's a lot of code to wade through, but here's how I'd generally do it:

 

1) form is sent

2) data is validated, images saved, etc

3) Reshow form with data

3a) When generating the FILE inputs, if one has a file already uploaded, don't show the FILE input for that one. Instead show a checkbox to delete the file and show the filename.

 

So if 3 pdf's/whatever were uploaded, the first 3 spots where you'd normally see the upload button would instead have a checkbox. The other remaining 7 inputs would show the upload.

 

Checking some or all of the checkboxes and resubmitting the form would delete/unlink() those files during step #1 above, and when the form is redisplayed, the upload slots would show up again in their place.

First, sorry (again) for the long code.

 

Sometimes, trying to show relevant code, you end up missing the really relevant code.

 

What you described is exactly what I am trying to do and I know that using unlink is the way to go but I am just not sure *where* to place the code given the code I showed above.

 

Any additional help is greatly appreciated.

Ok looking at your code I assume only the file paths are stored in the following fields?

BidIDFile     <--- stores the filepath for BidFile 	
TabSheet      <---    "    "     "      "  TabSheet	
SignInSheet   <---    "    "     "      "  SignIn Sheet
Addend1       <---    "    "     "      "  Addendum 1 
Addend2       <---    "    "     "      "      "	2 
Addend3       <---    "    "     "      "      "	3 
Addend4       <---    "    "     "      "      "	4 
Addend5       <---    "    "     "      "      "	5

I couldn't find what fields stores the filepath for the form fields labelled Addendum 6 and Executed Contract in your form?

 

 

I wont post the code for all 10 fields in your form. I will show an example for the Bid File field.

       <td class="td_input_form"><input type="file" name="BidIDFile[]" size="50"></td> 

Change the Bid File upload field (shown above) to to this

       <td class="td_input_form">
        <?php 
        // if the BidIDFile is empty, 
        if(empty($result["BidIDFile"]))
        {
            //then show file upload field for Bid File
            echo '<input type="file" name="BidIDFile[]" size="50">';
        }
        else
        {
            // Bid file already upload, show checkbox to delete it. 
            echo '<input type="checkbox" name="delete[]" value="BidIDFile"> Delete ' . $result["BidIDFile"];
        }
        ?>
       </td>

This will show the file upload field if a Bid File has not been uploaded (the BidIDFile column is empty in the table row). If there is a value then it will show a checkbox for deleting the file.

 

You will apply this code logic for the remaining upload fields. Changing BidIDFile to the corresponding column in your table for each field.

 

To delete the file you need to loop over $_POST['delete'] array when the form has been deleted. This array contains the table columns for each uploaded files. You would perform a select query to get the file paths from these columns in your table. From the result of the query you would pass each file path to unlink to delete the file. Then to remove the file paths from the table you would run an update query setting the columns to an empty value. Example code

// Connect to SQL Server database
include("connections/Connect.php");

$strsID = isset($_GET["Id"]) ? $_GET["Id"] : null;

if(isset($_POST['delete']))
{
    // whilelisted table columns
    $fileColumnsInTable = array( 'BidIDFile', 'TabSheet', 'SignInSheet', 'XConnect',
                                 'Addend1', 'Addend2','Addend3','Addend4','Addend5', 'Addend6');

    $fileColumns = array();
    foreach ($_POST['delete'] as $fileColumn)
    {
        if(in_array($fileColumn, $fileColumnsInTable))
            $fileColumns[] = $fileColumn;
    }

    // get the file paths for each file to be deleted
    $stmts = "SELECT " . implode(', ', $fileColumns) . " FROM bids WHERE ID = ? ";
    $querys = sqlsrv_query( $conn, $stmts, array($strsID));
    $files = sqlsrv_fetch_array($querys,SQLSRV_FETCH_ROW);
    
    // loop over the files returned by the query
    foreach ($files as $file )
    {
        //delete file
        unlink($file);
    }

    // now remove the values from the table
    $stmts = "UPDATE bids SET " . impload(' = '', ', $fields) . " WHERE ID = ? ";
    $querys = sqlsrv_query( $conn, $stmts, array($strsID));
}

Man, if this works, I owe YOU my life.

 

I have been working on this for days and I am supposed to give progress status on Monday during a meeting.

 

To answer your question as to whether path to the PDF files are stored on the DB, the answer is no.

 

Each is linked to the pdf file by fieldname. Above shows how each is linked.

 

This is just one:

 

 

 

Be back shortly with feedback...

 

Thank you so much

Delete ' . $result["BidIDFile"];

Hi again,

 

How do I convert this part from your solution to link above?

Not quite understanding you. I guess you want to replace the   Delete ' . $result["BidIDFile"];   after the checkbox with your link?

 

You can replace the checkbox line with this

            echo '<input type="checkbox" name="delete[]" value="BidIDFile">
            <a href="http://uploads/'.$result["BidFile"].'" target="_blank" onclick="window.open (this.href, \'child\', \'height=800,width=850,scrollbars\'); return false" type="application/octet-stream">'.$result["Addend4"].'</a>';

This is incredible. You are awesome. I feel like singing.

 

Amazing how someone you don't know can bring you some joy.

 

Only one issue I have left, if you don't mind is integrating your SELECT and UPDATE code into mine.

 

I do already have a code that either INSERTs or UPDATES depending on what operation a user wishes to perform.

 

I am having problem with that last bit.

 

I posted above (sorry long).  Or at least point in the right direction of where to fit your code in.
