Existing images disappear when updating

Help!
All pages created with DA. Followed directions for adding DFP to DA Insert and Update pages.
The Insert works fine. The files are uploaded and display on the results (thumbnail) and Detail (full size) and datbase gets an entry in the field.

The problem comes when any field on the form is updated. Unless the image file is re-browsed and uploaded, the image is not displayed on the Results and Detail and the database (thru myPHPAdmin) has been returned to NULL.

Thanks in advance.

Below is the code from the php portion of the update page

<?php
// WA_UploadResult1 Params Start
$WA_UploadResult1_Params = array();
// WA_UploadResult1_1 Start
$WA_UploadResult1_Params["WA_UploadResult1_1"] = array(
'UploadFolder' => "../himages/",
'FileName' => "[FileName]",
'DefaultFileName' => "",
'ResizeType' => "4",
'ResizeWidth' => "400",
'ResizeHeight' => "266",
'ResizeFillColor' => "#FFF5cc" );
// WA_UploadResult1_1 End
// WA_UploadResult1_2 Start
$WA_UploadResult1_Params["WA_UploadResult1_2"] = array(
'UploadFolder' => "../himages/thumb",
'FileName' => "[FileName]",
'DefaultFileName' => "",
'ResizeType' => "4",
'ResizeWidth' => "140",
'ResizeHeight' => "104",
'ResizeFillColor' => "#FFF5cc" );
// WA_UploadResult1_2 End
// WA_UploadResult1 Params End
?>
<?php?>
<?php
WA_DFP_SetupUploadStatusStruct("WA_UploadResult1");
if(isset($_POST["Update_x"])){
WA_DFP_UploadFiles("WA_UploadResult1", "Image1update", "0", "", "true", $WA_UploadResult1_Params);
}
?>

Markup
<td class="WADADataTableCell"><input type="hidden" name="Image1" id="Image1" value="<?php echo(str_replace('"', '&quot;', $row_WADAproperty['Image1'])); ?>" size="32" tabindex="6" />
<br />
<label>
<input type="file" name="Image1update" id="Image1update" />
</label></td>

After the post - I read some more and found the post about the enter key (post 5368)

Used it and the Default file changed to:
'DefaultFileName' => "".$WA_DFP_UploadStatus["WA_UploadResult1"]["serverFileName"] ."",

But still lost the database entry and display upon updating another field.

You are setting the default file to the server file name.


On the update page, you will create a hidden file field to hold the original file name ffrom the database. the default file should be set to use this hidden form elemetnt instead of the server file name.
