I'm curently struggling with a problem. I have an XML that is having 4 zeros after decimal in product dimensions and I need to remove the trailing zeros after the import...
Any ideas?
You can try running each value through a custom PHP function which will remove the trailing zeros. During the import replace the value (e.g. {price[0]}) with something like this:
[strip_trailing_zeroes_from_price({price[0]})]
Also write the actual code and insert into the Function Editor on the Edit Import page:
function strip_trailing_zeroes_from_price( $price = null ) {
if ( !empty( $price ) ) {
// strip trailing zeroes from price
}
return $price;
}

I am using a function.php code to convert all characters to uppercase when posting the "input" data for the Wordpress gravity forms plugin.
add_action('gform_pre_submission_1', 'capitalize_fields_1');
function capitalize_fields_1($form){
// add all the field IDs you want to capitalize, to this array
$fields_to_cap = array('input_1');
foreach ($fields_to_cap as $each) {
// for each field, convert the submitted value to uppercase and assign back to the POST variable
// the rgpost function strips slashes
$_POST[$each] = strtoupper(rgpost($each));
}
// return the form, even though we did not modify it
return $form;
}
However, I am using Turkish language and there is a character that is outside of UTF-8. The lowercase letter "i" becomes the letter "I" when converting. These two characters mean different things from each other. I want to convert the lowercase letter "i" into letter "I".
I found a php code for this process, but I could not adapt it to the function.php file.
function mb_strtoupper_tr($metin){
$metin=str_replace('i', 'İ', $metin);
Can anyone help me how to adapt this or implement a more efficient method?
add_action('gform_pre_submission_1', 'capitalize_fields_1');
function capitalize_fields_1($form){
// add all the field IDs you want to capitalize, to this array
$fields_to_cap = array('input_1');
foreach ($fields_to_cap as $each) {
// for each field, convert the submitted value to uppercase and assign back to the POST variable
// the rgpost function strips slashes
$_POST[$each] = strtoupper(str_replace('i', 'İ', rgpost($each)));
}
// return the form, even though we did not modify it
return $form;
}
I am try to use explode() on a string fetched from a database but it didn't work. I have tried explode('-',$string) but it's still not working.
Here is my string which I want to explode:
Expression of Interest – Join our Paint Team – North
If you look closely the hyphen from the string is not the same as the hyphen you use as your argument for the explode.
The hyphen in the string is the following – while the hyphen you pass as the argument for explode() is -. As you can see they don't match (the one in the string is longer than the one you try to compare it with). Because the characters don't match, the explode function is returning the whole string.
<?php
$string = "Expression of Interest – Join our Paint Team – North";
$strings = explode('–', $string);
var_dump($strings);
I have copied the hyphen from the text and used that as an argument for explode() and it works fine.
Might be $string is not string, you can use strval( $string ) to convert it to string i.e. explode('–', strval ( $string ) );
$eString = explode('–', strval ( $string ) );
// vardump($eString) - Now it is an array.
// echo $eString[0];
I have fix the issue by trying this
$post_job_title = htmlentities(get_the_title($posts));
$post_job_title = explode (" – ", $post_job_title);
I have a buddypress site and I have edited the activity stream to include the activities I want to see however it's more logical to filter out the unwanted so future plugins don't have to be manually included I have tried != but does not work.
<?php if ( bp_has_activities( bp_ajax_querystring( 'activity' ).'&action=bbp_reply_create,last_activity,gmw_location,activity_liked,rtmedia_update,new_avatar,updated_profile,joined_group,new_blog_post,bbp_topic_create,created_group' ) ) : ?>
And here is what I tried.
<?php if ( bp_has_activities( bp_ajax_querystring( 'activity' ).'&action!=friendship_created,new_member' ) ) : ?>
But the attempt simply left the whole stream blank.
I've never used Buddypress, but from what I see you cannot simply use the != operator. You are placing the != in a string that is the input for a function named bp_ajax_querystring(). From the function's name, and the rest of the input, it looks like a set of GET parameters.
GET parameters only allow the setting of attributes (so != has no meaning). Instead, place the ! in front of the expression being evaluated by the if statement:
if ( !bp_has_activities( bp_ajax_querystring( 'activity' ).'&action=bbp_reply_create,last_activity,gmw_location,activity_liked,rtmedia_update,new_avatar,updated_profile,joined_group,new_blog_post,bbp_topic_create,created_group' )
Is it possible to fetch a post with content under 140 characters or 25 words ?
if possible how to do it
here is my random post code
// Random post link
function randomPostlink(){
$RandPostQuery = new WP_Query(array('post_type'=>array('tip'),'posts_per_page' => 1,'orderby'=>'rand'));
while ( $RandPostQuery->have_posts() ) : $RandPostQuery->the_post();
echo the_permalink();
endwhile;
wp_reset_postdata();
}
Character count is easy, you can just add the condition AND CHAR_LENGTH(post_content) < 140 to your where clause.
Word count is more difficult because there is no built in MySQL function for counting words. You can find simple solutions that don't work in every use case as well as complete solutions that use stored functions. I'll use a simple solution for the sake of example.
What you need to do is add a filter to the where clause and apply your additional conditions there:
add_filter( 'posts_where', 'venki_post_length_limit' );
function venki_post_length_limit($where = '') {
remove_filter( 'posts_where', 'venki_post_length_limit' );
$where .= ' AND (
CHAR_LENGTH(post_content) < 140 OR
(LENGTH(post_content) - LENGTH(REPLACE(post_content, ' ', ''))+1) < 25
) ';
return $where;
}
Notice that I remove the filter as soon as the function is called. This is so you don't apply this same condition to every query.
You should also be aware that both of those conditions are costly compared to a simple lookup on a column value (especially the word count). Neither can utilize indexes. If you have a large number of posts you may run into performance issues if you're running this query frequently. A better solution might be to calculate the word and character count when the post is created/updated and store that as meta data.
I've got a number of custom fields in a WP theme, and I want to check if they have values - but would like a short cut to check multiple values at once - something like this:
if ( get_post_meta ( $post->ID, "first_value", "second_value", "third_value", $single = true) !="") :
// do stuff here, as they are all set ##
else:
// do something else, as they are not all set ##
endif;
this does not throw an error, but it only checks if the first value is set - any ideas?
First note the affects of setting the $single variable to true:
If $single is set to false, or left
blank, the function returns an array
containing all values of the specified
key. If $single is set to true, the
function returns the first value of
the specified key as a string, thus you can use string compare (not in an array)
Solution 1: That being said you could then use $single=false to get an array of values, and then compare the array of values to an array of null values.
Solution 2: Or you could use several conditions in the if_else statement:
if ( get_post_meta($post->ID,"first_value",true)!="" && get_post_meta($post->ID,"second_value",true)!="" && get_post_meta($post->ID,"third_value",true)!="") :
// do stuff here, as they are all set ##
else:
// do something else, as they are not all set ##
endif;
Solution 3: You could also use nested if_then statements if you prefer those.
The question is, which solution works best for you?
