I'm using Wordpress & Woocommerce and I want to add a div on my shop page, just above the ul list of products. I know that this command works in the functions.php file:
function woa_content_before_shop() {
echo "<h1>Hello</h1>" ;
}
add_action( 'woocommerce_before_shop_loop', 'woa_content_before_shop');
But when I replace the h1 tags with div tags it crashes. Can anyone tell me what I've doing wrong and/or how to correct this please? Thanks in advance!
if I replace echo "<h1>Hello</h1>" ; with echo "<div class"title">Hello</div>" ; the page fails to load – T.Doe 15 secs ago
that's because you did not escape the inner double quotes in there.
So do: (and you forgot an = sign after class)
echo "<div class=\"title\">Hello</div>" ;
and it will work.
Or
echo '<div class="title">Hello</div>' ;
in single quotes
Best is that you use the "template overwrite" method:
Copy the woocommerce/templates/ folder inside your theme folder, to yourtheme/woocommerce/
Inside that folder, you can modify the html structure to your heart's content and it will be used instead of woocommerce standard html templates.
Once this is done, open up these two files:
/wp-content/themes/your-theme/woocommerce/shop/wrapper-start.php
/wp-content/themes/your-theme/woocommerce/shop/wrapper-end.php
and modify the html to match yours.

I tried following the information here, editing it to match my needs, but so far it's not working.
I'm trying to hide a parent div with two child elements. The parent div is part of a list, all with the same classes, and each div has two child elements: an input, and an image. Each input has a unique "data-wapf-label" that I'm trying to select so that I can hide the parent div. The HTML is as follows:
<div class="has-pricing wapf-swatch wapf-swatch--image">
<input type="radio" id="wapf-field-61b148f2fc8fe_lzhx7" name="wapf[field_61b148f2fc8fe]" class="wapf-input" data-field-id="61b148f2fc8fe" value="lzhx7" data-wapf-label="Peppermint Mocha" data-is-required data-wapf-pricetype-"fx">
<img src="...">
</div>
There are several pages where this product shows up, and rather than going in and deleting the product field (because I'll just have to add it again next season), I'm trying to create a piece of code that will hide all the divs for all the products that have the above code (since each has a unique "id", I'd have to do it several times for each id using "selectElementById", and I'd like to avoid doing that, obviously).
I installed Code Snippets, but I'm having a bit of trouble with the Javascript. I should add that Code Snippets inserts code to the website via php (so php tags are required with every snippet). I've tried several things, but this is my latest version. It throws a syntax error "unexpected 'hideFlavors' (T_STRING), expecting '('".
Here's my php/Javascript code:
<?php
add_action( 'wp_head', function hideFlavors() { ?>
<script>
if var peppermintMocha = document.querySelectorAll("[data-wapf-label='Peppermint Mocha']") {
peppermintMocha.parentNode.style.display = "none";
}
</script>
<?php } );
I've also tried it with "document.querySelector" (without the "All"), but with the same or similar problem. When I do get the code to actually go through without any errors, it still doesn't fix the problem.
At this point, I feel a little like the guy looking through the tank's periscope on "Independence Day". No matter what I do, "target remains".
<?php
add_action( 'wp_head', function() {
?>
<script>
window.onload = function() {
document.querySelectorAll("[data-wapf-label='Peppermint Mocha']").forEach(function(el) {
el.parentNode.style.display = "none";
});
};
</script>
<?php
});
?>
querySelectorAll returns an array of elements, so you need to loop through each element and hide their parent respectively.
Instead querySelectorAll use querySelector. Then it would be work. But make sure that exists only one input field with the selector [data-wapf-label='Peppermint Mocha'].
I have a table that displays items from a database. One of the items is a description so it can be very long.The thing I'm having the most problem with is how can I use JS and HTML smoothly in my controller class.
I want to be able to display a little bit of it if its longer than 100 char, and a button that looks like '...' where if the user clicks on it, it displays the trimmed text. I want to do this using javascript and here is what I tried, this code is in my controller, so I'm just sending these to the view.
The problem is when I press the button it doesn't display anything so what is wrong here? Some suggested to use jquery but I don't want to write my js script elsewhere and call it again since I'm not sure how I will do that in Phalcon controller.
$this->view->tblColumns = [
'element one',
'element two',
function (tablename $instance) {
if (strlen($desc = $instance->getDescription()) > 100) {
return $shortDesc = substr($instance->getDescription(), 0, 100) . '
<button style="background: none;border: none" onclick="(function(){
var desc= <?php echo
$desc; ?>; document.write(desc) ;
})()" >...</button>';
} else {
return $instance->getDescription();
}
},
do NOT use document.write after load of the page. It will wipe the page
your desc needs to be in single quotes and have no carriage returns.
you cannot use an IIFE in an onclick unless it returns a function
if your button is in a form, you will submit the form - it should be type=button
You MAY mean
<button type="button" onclick="var desc='<?php echo $desc; ?>';
document.querySelector('#someContainer').innerHTML=desc;"...>
but a better way is to toggle the existing text inside tags (span for example)
I find a way to do what I wanted, using the code for read more,read less from this link https://codepen.io/maxds/pen/jgeoA
The thing I was having trouble with in phalcon MVC, was that I didn't know I could my java-script, and css in the view of the controller and that's what I did.
I just used the js from that link, into my view file, the same for the css using tag and tag.
And in the function on the controller I wrote the following `
$this->view->tblColumns = [
'one',
'two',
function(tablename $link){
$desc=$link->getDescription();
$html=<<<HTML
<span span class="more"> $desc</span>
HTML;
return $html;
}`
I have an html text called news which is generated by ckeditor, so it may contain html tags like bold, italic, paragraph and....
I want to choose the first 100 characters of it and show them to the users of my app. but choosing the first 100 characters of news may cause to choose an html text which has unclosed tags(the closing tags of my html text may be after the character number 100).
is there any PHP or js function to parse a text and fix the unclosed html tags or at least remove unclosed html tags?
As far as removing tags altogether, the strip_tags function in PHP should do the trick.
strip_tags($input, '<br><br/>');
The second argument is the allowed tags (the ones that don't get stripped).
Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipulate HTML documents, but also traverse the document tree.
Try this
You could remove the HTML Tags by using the PHP function strip_tags().
<?php
$text = '<h1>Test Header. <b>On Example</b>';
echo strip_tags($text);
// Output: Test Header. On Example
?>
Please check the reference on the function at https://secure.php.net/strip_tags
Side Note:
I have a function to chopContent that you could use, to get the first 100 characters:
public function chopContent($content, $content_length = 100)
{
if (strlen($content) > $content_length) {
$offset = ($content_length - 13) - strlen($content);
$content = mb_substr($content, 0, strrpos($content, ' ', $offset)) . '...';
}
return $content;
}
I have a webpage where admin users can edit the text on the page. But when they insert the text into the mysql database, it sometimes adds more and more white spaces before the acual content.
If you place your cursur before the first word on the page and spam backspace for a while, the whitespace in the database dissappears. But over time, the more you keep editing the page, more and more whitespaces are added again.
I did a lot of trouble shooting, but I just can't figure out what causes the whitespaces to be added. It does not always happen making it really difficult to troubleshoot.
Here's my code:
As my code is pretty long, I tried to translate most of the content to english.
If you want to translate something that in't already translated, the original language is Dutch.
over_ons.php - Shows edit button and page content from the database.

//If the system is in edit mode and the user tries to leave the page,
//let the user know it is not so smart to leave yet.

SOLUTION
Thanks to the great help of a lot of people, and especially #avnishkgaur, it is working perfectly now. Here is what I ajusted (also changed it in my code above, so that's working code now).
1. Removed all the white spaces I had in my code between <div id='editable'> and <?php
2. Added $tekst = trim($tekst); to my PHP file to remove white spaces (didn't work)
3. Placed the editable text into another div as the code for getting the data from the database (was in the same div before)
4. Renamed the ID from the editable div to editedText. Also changed the name in the javascript file. This solution made it work perfectly (it was 'editable' before).
This was kind of an unexpected solution, so I think this could help others too.
As to why it is adding extra whitespace, I think it is because you are inserting the text from database into div directly (which contains some white space in html code, which is removed when page is rendered).
One efficient solution would be to insert your content in tag, probably like this:
<div class='big_wrapper'>
<p id='editable'></p>
</div>
Another solution is to trim the text before inserting into db. You can do that either at javascript post stage, or right before inserting in mysql db.
In jQuery, (which you are using) you can implement this :
data: 'tekst=' +$.trim(div_inhoud)+ '&pagina=' +pagina+ '&editor=' +$.trim(editor),
or in sent_data.php, you can use TRIM mysql function in your update query.
First of all, I would strongly suggest to use mysqli or PDO instead of the mysql functions in PHP, as these are deprecated. Please look into this on PHP.net.
As for your problem, I have no tried to reproduce the issue. I suggest you log and check what happens step by step, for example logging the div_inhoud var, are the spaces included at this stage already? And so on.
If you are in a hurry, you could also use the PHP function ltrim on the $tekst var in your sent_data.php, which would trim all spaces on the left side (Or any characters you would want to be trimmed from the string)
Try to add a trim() function in your send_data.php, this will help you to strip white spaces.
$tekst = trim($_POST['tekst']);
My guess is that the newlines after the <div id='editable'> and ?> and the indentation of <?php in over_ons.php is adding the extra whitespace. Specifically, a couple of extra /n's and also spaces from the indentation within the file.
You could trim the whitespace before saving it to your database, or alternatively, before the ajax call, or both.
In php, trim():
sent_data.php
$tekst = trim($tekst);
Or javascript, str.trim():
javascript.js
var div_inhoud = $("#editable").html().trim();
Also, you may want to consider using PHP Data Objects, instead of inserting variables directly into your SQL statements. It's actually really easy to use and in my opinion makes code easier to read and more reusable. There is a fantastic tutorial by Tuts+ that makes it easy to learn and get started. This will ensure you don't accidentally allow SQL injection issues into your application.
JQuery seems to be blocked
Hello there, I've been confronting this problem for several days, I just can't find a way to get this fixed, or around it.
What I want to do is simple, I want to read out every sub-folder of a big Project folder. Then assign a thumbnail image and a figcapture to this folder. With a simple for loop, php builds this for me. Everything works perfect and quick. The only thing is that the jquery won't respond. Even though I have created various menus with this technique. As you can see in my code, in the "script" tags, I have the jquery code which doesn't seem to work.
I don't know wheter php puts in a space somewhere or I just looked too long at this code for seing the error.
I appreciate any help.
<?php
/*Because of the "ease of use" aspect of this site, I prefered to write it completely in PHP,
advantage of that:
Images are loaded directly out of the folder, so I can just drag and drop something onto the server without having to write aditional code.

echo "<h1>Referenzen</h1><br>";
$projects = scandir('../src/sub/credentials'); //The credentials directory is being scanned and converted into an array.
$projectsSize = count($projects); //$size is being created. It counts the number of objects in the array which has been created above.
$projectsCaptions = file('../src/sub/captionsOfCredentials.txt'); //Edit the name of the figcaption in the "captionsOfCredentials.txt".
for($i = 2; $i < $projectsSize; $i++){ /*Simple "for" loop, that creates $i with the size of two, because PHP is 0-index based and has the "dot" and the "dotdot" folder. The loop stops at the end of the array($size).*/

$('#ID".$projectsCaptions[$i]."').click(function () {
$('#mainContent').load('de-DE/".$tempID."');
});
});
</script>";
}
//end first for-loop
?>
You're selecting an element by id when you need to use class. Change the JS block to this:
$(document).ready(function () {
// Note ".ID" not "#ID"
$('.ID".$projectsCaptions[$i]."').click(function () {
$('#mainContent').load('de-DE/".$tempID."');
});
});
UPDATE
It seems like you've also got an illegal character in $projectsCaptions[$i]. It's most likely a newline character. Try wrapping the above reference above in trim():
$('.ID" . trim($projectsCaptions[$i]) . "').click(function () {
