I am php MySQL developer and WordPress theme / plugin developer also. So i create a plugin for products catalogue and upload images more than one. In my older versions i give option in plugin settings page that user can set dimensions for big and thumb images and on front i just re-size images width and height in css with giving dimensions but all images get stretched. Many users complain about this issue.
I searched re-sizing images and found out this function of WordPress
Code: Select all
wp_get_image_editorHere is code sample:
Code: Select all
$upload_dir = wp_upload_dir();
$_image_width = get_option('_image_width');
$_image_height = get_option('_image_height');
$_thumb_width = get_option('_thumb_width');
$_thumb_height = get_option('_thumb_height');
$_product_images = get_post_meta($post->ID, 'product_images', true);
$big_img_name = array();
$thumb_img_name = array();
foreach ($_product_images as $_prod_img) {
/// For Big
$big_resize_img = wp_get_image_editor($_prod_img['product_img']);
if (!is_wp_error($big_resize_img)) {
$product_big_img = $_prod_img['product_img'];
$product_img_explode = explode('/', $product_big_img);
$product_img_name = end($product_img_explode);
$product_img_name_explode = explode('.', $product_img_name);
$product_img_name = $product_img_name_explode[0];
$product_img_ext = $product_img_name_explode[1];
$big_crop = array('center', 'center');
$big_resize_img->resize($_image_width, $_image_height, $big_crop);
$big_filename = $big_resize_img->generate_filename('big-' . $_image_width . 'x' . $_image_height, $upload_dir['path'], NULL);
$big_resize_img->save($big_filename);
$big_img_name[]['_big_img'] = $upload_dir['url'] . '/' . $product_img_name . '-big-' . $_image_width . 'x' . $_image_height . '.' . $product_img_ext;
}
update_post_meta($post->ID, '_big_images', $big_img_name);The images cropped very successfully and save images path in the DB. So i launch the plugin's new version and and it worked very perfectly for users except one !!!!
. The images not re-sized when he upgrade from older to newer version.I checked and debug the code on this site. When i print this variable "$big_resize_img" its print me this message
Code: Select all
WP_Error Object
(
[errors] => Array
(
[invalid_image] => Array
(
[0] => El archivo no es una imagen.
)
)
[error_data] => Array
(
[invalid_image] => http://www.siteurl.com/wp-content/uploads/Wallpaper_1.jpg
)
)I asked to user that, is ImageMagick is enable on his server he told me yes, so i asked him to create a php file and write "php_info()" and execute this file. The output not show us ImageMagick lib just GD lib is enabled, so again i asked the user for this he create another php file and write code to show ImageMagick version etc.
Code is:
Code: Select all
<?
//This function prints a text array as an html list.
function alist ($array) {
$alist = "<ul>";
for ($i = 0; $i < sizeof($array); $i++) {
$alist .= "<li>$array[$i]";
}
$alist .= "</ul>";
return $alist;
}
//Try to get ImageMagick "convert" program version number.
exec("convert -version", $out, $rcode);
//Print the return code: 0 if OK, nonzero if error.
echo "Version return code is $rcode <br>";
//Print the output of "convert -version"
echo alist($out);
?>Code: Select all
Version return code is 0

So, Please tell me what is the issue because i launched newer version 4 months before and only this user get this issue. His site url is http://www.tentebien.com/
One More thing, is this possible if i disable the imagemagick lib but wp_get_image_editor still working because i search and almost every site tells me that the ImageMagick or GD lib is compulsory for 'wp_get_image_editor', so i don't get the point because i disable ImageMagick lib on my server but its still working.
Please tell me what is the issue because this issue has been occurring for three weeks now
