Hi,
I know its not a good idea to use blobs in mysql so now im saving a path in mysql table but im wondering if there is a away to have phpMyEdit show the image from the server in the table using the path instead of the actual binary data?
Thank you in advance,
Robert

No image handling functions are built into phpMyEdit.
From an ancient project, I used this schema to save image details including the image type.
| Code: |
CREATE TABLE IF NOT EXISTS `vs_inventory1` (
`id` mediumint(6) unsigned NOT NULL AUTO_INCREMENT,
`item_name` varchar(255) NOT NULL DEFAULT '',
`item_category` varchar(25) NOT NULL DEFAULT '',
`catid` smallint(5) unsigned NOT NULL DEFAULT '0',
`item_sub_cat` varchar(25) NOT NULL DEFAULT '',
`scatid` smallint(5) unsigned NOT NULL DEFAULT '0',
`item_number` varchar(20) NOT NULL DEFAULT '',
`item_description` text NOT NULL,
`on0` varchar(25) NOT NULL DEFAULT '',
`os0` varchar(255) NOT NULL DEFAULT '',
`on1` varchar(25) NOT NULL DEFAULT '',
`os1` varchar(255) NOT NULL DEFAULT '',
`amount` float(10,2) NOT NULL DEFAULT '0.00',
`weight` float(8,2) unsigned NOT NULL DEFAULT '0.00',
`shipping1` float(8,2) NOT NULL DEFAULT '0.00',
`shipping2` float(8,2) NOT NULL DEFAULT '0.00',
`tax` float(6,2) NOT NULL DEFAULT '0.00',
`taxable` tinyint(1) unsigned NOT NULL DEFAULT '0',
`addx` smallint(5) unsigned NOT NULL DEFAULT '1',
`currency_code` varchar(8) NOT NULL DEFAULT 'USD',
`image` mediumblob NOT NULL,
`image_width` smallint(5) unsigned NOT NULL DEFAULT '0',
`image_height` smallint(5) unsigned NOT NULL DEFAULT '0',
`image_type1` tinyint(2) unsigned NOT NULL DEFAULT '0',
`image_type2` varchar(20) NOT NULL DEFAULT '',
`img_attrib` varchar(30) NOT NULL DEFAULT '',
`hidden` tinyint(1) unsigned NOT NULL DEFAULT '0',
`last_modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
UNIQUE KEY `item_number_2` (`item_number`),
KEY `catid` (`catid`),
KEY `scatid` (`scatid`),
KEY `item_name` (`item_name`)
) ENGINE=MyISAM; |
A regular PHP script was used to grab the image:
| Code: |
<?php
// getimage.php
$id = array_key_exists('id', @$_GET) ? @$_GET['id'] : '';
if(is_numeric($id)){
$data = '';
$type = '';
// add your database connection here
$res = @mysql_query('SELECT image, image_type2 FROM vs_inventory1 WHERE id = '.$id);
$data = @mysql_result($res, 0, 'image');
$type = @mysql_result($res, 0, 'image_type2');
@header("Content-type: $type");
echo $data;
}
?> |
The PHP/HTML code used to fetch the image is:
| Code: |
| <img src="getimage.php?id=<?php echo $id; ?>" alt="<?php echo htmlspecialchars($item_name); ?>" border="0" <?php echo $img_attrib; ?>> |
Storing images in MySQL is (IMHO) a huge waste of time, very inefficient, especially if recalling more than one image on a page due to multiple db connections having to be made.

Search the forum for CONCAT
With path information stored in the db, examples can be found for creating custom HTML tags for A tags, IMG tags, etc., using the MySQL CONCAT function.
| Code: |
$opts['fdd']['dummy2'] = array (
'name' => 'Thumbnail',
'sql|VLF' => 'if(category = "other",
CONCAT("<a href=\"", dir, "/", filename, "\" target=\"_blank\">link</a>"),
if(category = "thumb", CONCAT("<a rel=\"example_group\" href=\"", REPLACE(dir, "/tn", "/"), filename, "\" target=\"_blank\"><img src=\"", dir, "/", filename, "\" ", " alt=\"\" border=\"0\"></a><br><a href=\"fancybox.change.php?upld_id=", upld_id, "\">Replace</a>"), ""))',
'options' => 'VLF',
'input' => 'R',
'escape' => false,
'sort' => false
); |
| Code: |
$opts['fdd']['virtual_field'] = array (
'name' => 'Thumbnail',
'sql|VLF' => 'if(mime_type = "image/jpeg", CONCAT("<a rel=\"example_group\" href=\"", REPLACE(dir, "/tn", "/"), filename, "\" title=\"", text_1, "\" target=\"_blank\"><img src=\"", dir, "/", filename, "\" ", " alt=\"\"></a>"), "")',
'options' => 'VLF',
'input' => 'R',
'escape' => false,
'sort' => false
); |

Hi I'm trying to use the path (ex. Pictures/file.jpg) in another column to show the image in the next column in the row like a thumbnail. I tried the Coe before but it didn't work. Also I'm trying to put the picture which is actually in a folder with the phpMyEdit file. Thanks,
Robert

"Pictures/file.jpg" is data in a database table, right?

Adding one of these to the field array for your_field_name should work, i.e. use the second one (with ../) if the Pictures folder is one directory level above the phpMyEdit script.
| Code: |
'sql|VLF' => 'if(your_field_name <> "", CONCAT("<img src=\"", your_field_name, "\" ", " alt=\"\">"), "")',
'sql|VLF' => 'if(your_field_name <> "", CONCAT("<img src=\"../", your_field_name, "\" ", " alt=\"\">"), "")', |

Thank you very much, it worked, and looks great :)
Just for reference I also added height and border so it would fit nicely in the column. Ended up like this:
'sql|VLF' => 'if(Filename <> "", CONCAT("<img src=\"", Filename, "\" ", " alt=\"\"height=75 border=0>"), "")',

Yes, it is possible to display

images in phpMyEdit using the path stored in a MySQL table instead of the actual binary data.

In the example above, replace "path/to/your/image.jpg" with the actual file path or URL of the site https://remedialshrooms.com/ for image you want to display. When this PHP code is executed, it will generate HTML output that includes the image tag, and the specified image will be displayed in the browser.
