Second add_action function is not working but I am not getting any error. if I take the second add_action out of the function it works outside but since I want it to work on specific pages I can't work with that.
Do you have any suggestion how may I fix this problem?
add_action('current_screen', function ($current_screen) {
if ('smart_board' == $current_screen->post_type && 'post' == $current_screen->base) {
add_action('add_attachment', function ($post_ID) {
$file = get_attached_file($post_ID);
$path = pathinfo($file);
$file_slugified_name = $path['filename'];
$file_prefix = 'smart_board_';
$file_dir = $path['dirname'];
$file_extension = $path['extension'];
$newfilename = $file_prefix . $file_slugified_name;
$newfile = $file_dir . "/" . $newfilename . "." . $file_extension;
rename($file, $newfile);
update_attached_file($post_ID, $newfile);
});
}
});

I need to set it by the technical task.
I've found only
function hrefs_to_uppercase($hrefs) {
$hrefs = array_change_key_case($hrefs,CASE_UPPER);
return $hrefs;
}
add_filter( 'wpml_hreflangs', 'hrefs_to_uppercase' );
But it makes all characters uppercase - "EN-AE".
Tried manually in wpml settings- didn't help
You can simply replace the array key with the following code:
function hrefs_to_uppercase($hrefs) {
$hrefs['en-AE'] = $hrefs['en-ae'];
unset($hrefs['en-ae']);
return $hrefs;
}
add_filter( 'wpml_hreflangs', 'hrefs_to_uppercase' );
if you want to make every array key have an uppercase second part (e.g. from en-us to en-US), you can use the codes below (assumed all your keys have a similar structure like en-us):
function hrefs_to_uppercase($hrefs) {
foreach ($hrefs as $key => $val) {
$key_tokens = explode('-', $key);
$new_key = $key_tokens[0] . '-' . strtoupper($key_tokens[1]);
$hrefs[$new_key] = $hrefs[$key];
unset($hrefs[$key]);
}
return $hrefs;
}
add_filter( 'wpml_hreflangs', 'hrefs_to_uppercase' );
I solved like that for now, maybe right-maybe not
jQuery('[hreflang*="en-ae"]').each(function(){
// Update the 'rules[0]' part of the name attribute to contain the latest count
jQuery(this).attr("hreflang",'en-AE');
});
I installed Excelbundle with PhpExcel library. I want to read excel files I found this function.
How can I use it? Any suggestion?
public function xlsAction()
{
$filenames = "your-file-name";
$phpExcelObject = $this->get('phpexcel')->createPHPExcelObject($filenames);
foreach ($phpExcelObject ->getWorksheetIterator() as $worksheet) {
echo 'Worksheet - ' , $worksheet->getTitle();
foreach ($worksheet->getRowIterator() as $row) {
echo ' Row number - ' , $row->getRowIndex();
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // Loop all cells, even if it is not set
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
echo ' Cell - ' , $cell->getCoordinate() , ' - ' , $cell->getCalculatedValue();
}
}
}
}
}
My suggestion is "Read the documentation" and start hacking at it. Working with excel is, in my experience, quite complex and time consuming so don't expect other people to solve your problem online.
It seems like you're talking about this bundle:
https://github.com/liuggio/ExcelBundle
It has great documentation, even full examples (see "Fake Controller").
With PHPExcel it is quite easy to read a Excel document.
See my example :
$dir = $this->getContainer()->getParameter("kernel.root_dir") . "/../../data/import/";
$file_name = "my_excel_file.xlsx";
$excel = $this->getContainer()->get('phpexcel')->createPHPExcelObject($dir . DIRECTORY_SEPARATOR . $file_name);
$sheet = $excel->getActiveSheet();
$row = 0;
while ($sheet->getCellByColumnAndRow(1, $row)->getValue()) {
$data = $sheet->getCellByColumnAndRow(2, $row)->getValue(); // get value from nth line and 2nf column
//do stuff -- see doc for functions on $sheet
}
i tried to set the taxonomy of a post but it always return invalid_taxonomy error.
$categorys_ids = wp_set_object_terms($post_id, $categorys, 'categorie-video');
error_log('categorys brut = ' . $data['category'] .'postid '.$post_id.'categorys = ' . json_encode($categorys_ids));
//byme
if (is_wp_error($categorys_ids)) {
error_log('categorys =There was an error somewhere and the terms couldn\'t be set');
} else {
error_log('categorys =Success! The post\'s categories were set.');
}
I am trying to rename upload filenames match the Post Title.
This other thread shows how to rename to hash:
Rename files during upload within Wordpress backend
Using this code:
function make_filename_hash($filename) {
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$name = basename($filename, $ext);
return md5($name) . $ext;
}
add_filter('sanitize_file_name', 'make_filename_hash', 10);
Does anyone know the code to rename the file to match Post Title.extension?
barakadam's answer is almost correct, just a little correction based on the comment I left below his answer.
function new_filename($filename, $filename_raw) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
$new = $post->post_title . $ext;
// the if is to make sure the script goes into an indefinate loop
if( $new != $filename_raw ) {
$new = sanitize_file_name( $new );
}
return $new;
}
add_filter('sanitize_file_name', 'new_filename', 10, 2);
Explanation of code:
Lets assume you upload a file with the original filename called picture one.jpg to a post called "My Holiday in Paris/London".
When you upload a file, WordPress removes special characters from the original filename using the sanitize_file_name() function.
Right at the bottom of the function is where the filter is.
// line 854 of wp-includes/formatting.php
return apply_filters('sanitize_file_name', $filename, $filename_raw);
At this point, $filename would be picture-one.jpg. Because we used add_filter(), our new_filename() function will be called with $filename as picture-one.jpg and $filename_raw as picture one.jpg.
Our new_filename() function then replaces the filename with the post title with the original extension appended. If we stop here, the new filename $new would end up being My Holiday in Paris/London.jpg which all of us know is an invalid filename.
Here is when we call the sanitize_file_name function again. Note the conditional statement there. Since $new != $filename_raw at this point, it tries to sanitize the filename again.
sanitize_file_name() will be called and at the end of the function, $filename would be My-Holiday-in-Paris-London.jpg while $filename_raw would still be My Holiday in Paris/London.jpg. Because of the apply_filters(), our new_filename() function runs again. But this time, because $new == $filename_raw, thats where it ends.
And My-Holiday-in-Paris-London.jpg is finally returned.
Something like this? (considering $post is your post variable, make it global):
function new_filename($filename) {
global $post;
$info = pathinfo($filename);
$ext = empty($info['extension']) ? '' : '.' . $info['extension'];
return $post->post_title . $ext;
}
add_filter('sanitize_file_name', 'new_filename', 10);
Did I understand you?
I'm totally new to WordPress so be easy :)
I the following code in a template:
<?php excerpt(20);?>
What this does is limit the text with 20 words. I am now wondering if there is some sort of similar function that limits by characters instead of words?
Thanks!
I use this:
add_filter('excerpt_length', 'my_excerpt_length');
function my_excerpt_length($length) {
return '500';
}
function better_excerpt($limit, $id = '') {
global $post;
if($id == '') $id = $post->ID;
else $id = $id;
$postinfo = get_post($id);
if($postinfo->post_excerpt != '')
$post_excerpt = $postinfo->post_excerpt;
else
$post_excerpt = $postinfo->post_content;
$myexcerpt = explode(' ', $post_excerpt, $limit);
if (count($myexcerpt) >= $limit) {
array_pop($myexcerpt);
$myexcerpt = implode(' ',$myexcerpt).'...';
} else {
$myexcerpt = implode(' ',$myexcerpt);
}
$myexcerpt = preg_replace('`\[[^\]]*\]`','',$myexcerpt);
$stripimages = preg_replace('/<img[^>]+\>/i', '', $myexcerpt);
return $stripimages;
}
And then in my theme file, I just call it in with:
better_excerpt('50') //50 being how many words I want
Useful for custom plugins/widgets too.
Wordpress doesn't support the character delimiter for the excerpt method, there's a plugin called Advanced Excerpt that does. After installing you can call the_advanced_excerpt('length=20&use_words=0')
I use this in my functions.php:
function truncate ($str, $length=10, $trailing='...'){
// take off chars for the trailing
$length-=mb_strlen($trailing);
if (mb_strlen($str)> $length){
// string exceeded length, truncate and add trailing dots
$str = mb_substr($str,0,$length);
$str = explode('. ',$str);
for( $i=0; $i<(sizeof($str)-2); $i++ ):
$newstr .= $str[$i].". ";
endfor;
return $newstr;
} else{
// string was already short enough, return the string
$res = $str;
}
return $res;
}
It should truncate to a character count, but then truncate back further to the last period before the truncation. It does get problematic when your excerpt includes links, however, or other markup - in other words, it's best to use the Excerpt field in the post rather than auto-excerpting with this function, because you can't use HTML in the excerpt field.
Please use this code for limiting post content...
<?php substr($post->post_content, 0, xy); ?> ...
Change the limit of XY....
