I'm trying to highlight the currently selected link in a link-bar, whereas the other links that are not selected should stay as they were. My idea is to assign a class within an if-statement (e.g. if the link contains the string "date=3", it will be assigned to class "selected) in order to style it then in CSS. But I dunno how it's done, can you help me please?
My hyperlink within PHP looks this way:
<?php echo date("l, j F",strtotime($mayday)+60*60*24*3); ?>
In your example, the link will always include date=3 !
But you want to evaluate if $_SERVER['REQUEST_URI'] contains date=3 ?
<a'.(preg_match("|date=3|",$_SERVER['REQUEST_URI']) ? "class=\"selected\"" : "").' href="<?php echo preg_replace("/&date=()/", "", $_SERVER['REQUEST_URI'])."&date=3";?>"><?php echo date("l, j F",strtotime($mayday)+60*60*24*3); ?></a>

I have a database table that contains these rows, "id" ,"link" and "name"
with link being :
<a href=\"https://www.sample.com/file1.php\">[1-200]< /a> <a href=\"https://www.sample.com/file2.php\">[201-224]< /a>
and name :
item1
I have the following PHP code to get the info from the database and return it to visitors. My problem is that the link for file2.php, is not only applied as hyper link for [201-224], the hyperlink is applied for the rest of the page content also. How do I prevent this? And thanks in advance.
echo "</br> ".$name= $row['name'];
echo "</br> ".$Torrentlink= preg_replace('/\\\\/', '',$row['Torrentlink']);
echo "</br> ";
echo "</br> ";echo "</br> ";
echo "the rest of my text goes here ";
This is a terrible way to handle this type of data. If you know they are all links then you should only be storing the link and the name (of course id and other meta data could be useful). Your current situation allows for too many errors and a maintenance problem for those working behind you. If you do not want to create a record for each link, consider storing them as JSON or some other format.
Example: (Store JSON in DB as VARCHAR)
<?php
//Populate variable from DB
//$TorrentLinks = $row{'Torrentlink'};
$TorrentLinks = '[
{"url":"https://www.sample.com/file1.php","text":"[1-200]"},
{"url":"https://www.sample.com/file2.php","text":"[201-224]"}
]';
//Convert to array
$jsonLinks = json_decode($TorrentLinks,true);
//Iterate and print links
foreach ($jsonLinks as $key => $value) {
echo "{$value["text"]}<br />";
}
Results:
[1-200]
[201-224]
Depending on how you capture the data, you could also use something like htmlspecialchars() to keep the special characters from executing.
I think there's a problem with your preg_replace('/\\\\/', '',$row['Torrentlink']);
/\\\\/ finds text with double backslash \\. It seems that your intention is to find only single backslashes to get rid of them in your links.
So try replacing it with
preg_replace('/\\/', '',$row['Torrentlink']);
For example https://regexr.com/ is a good place to check your regular expressions.
the error was simply the input html text.
the problem was the " < /a> " in the line:
<a href=\"https://www.sample.com/file1.php\">[1-200]< /a> <a href=\"https://www.sample.com/file2.php\">[201-224]< /a>
I had a space before the the backslash.
I'm a little lost here, hoping that someone can help. I'm using the Meta Box plugin for WordPress, and I'm trying to create a process for the user to select an option from a predefined list, and then assign a URL to that option as a link. Im trying to define the URL in a variable, and then call it in a function, but I'm still a little green on PHP syntax. this is my code now:
<?php
$article_url= rwmb_meta('orion_2016_article_url', 'type=URL');
if (rwmb_meta('orion_2016_article_source') != '') {
echo '<a href= ("$article_url") target=blank>';
echo rwmb_meta('orion_2016_article_source');
echo '</a>';} ?> on <?php the_date(); ?>
Since the options are already predefined, it seems like assigning a random URL to one of the options should be pretty simple. Hopefully this makes sense!
You need to to place variables you wish to echo inside double quotes or simply concatenate strings using . as in my example. Note that I didn't check the plugin's specific syntax, only general PHP syntax.
<?php
$article_url= rwmb_meta( 'orion_2016_article_url', 'type=URL' );
if (rwmb_meta('orion_2016_article_source') != '') {
echo '' . rwmb_meta( 'orion_2016_article_source' ); . '';
} ?> on <?php the_date(); ?>
I'm trying to find the category ID of a post and then use it in the short code below. To find the category id I'm using <?php the_category_ID(); ?>, but i'm not sure how to use the output from category id and replace it in include_categories=. i.e. i want to replace number 4 with the current category ID i got from <?php the_category_ID(); ?>.
<?php echo do_shortcode('[include_categories="4"]'); ?>
i tired doing the following, but it didn't work. Any ideas will be appreciated.
<?php echo do_shortcode('[include_categories="<?php the_category_ID(); ?>"]'); ?>
I know i can't use php inside another php code, but i'm not sure how to place the category id between the quotation.
Thanks.
A couple of things: (1) you can't have nested <?php ?> tags, (2) the_category_ID() has been deprecated since WordPress 0.71. You'll want to use get_the_category() instead.
The correct solution would be:
<?php echo do_shortcode('[include_categories="' . get_the_category() . '"]'); ?>
The dots . "concatenate" the string with the returned values of get_the_category(). You can read more about string operators in the PHP docs.
Try with -
<?php echo do_shortcode('[include_categories="'.the_category_ID().'"]'); ?>
Use this to add php verial in short code:
<?php $category=the_category_ID();
echo do_shortcode("[include_categories=$category]"); ?>
Can i put class name in title of div? It's possible?
<div class="flag brasileña" title="phpcode"></div>
I want put in title, text of second class "brasileña" with php code or similar
<?php
$className = "flag brasileña";
$alt = explode(" ", $className);
?>
<div class='<?php echo $className ?>' title='<?php echo $alt[1] ?>'></div>
Assuming class name always has two words and alt always take the second word and since you mentioned you want to do it by php the class name is generated dynamically.
This is how you can do it but this wont serve any purpose.
Whats that you want to do with adding second word to "alt".
this is the code where it load my dynamic menu
<?php echo $this->dynamic_menu->build_menu('1'); ?>
this is the code for my language type
<?php echo lanchor($uri, lang('menuenglish')); ?>
here i wanto to add like this
<?php echo $this->"<?php echo lanchor($uri, lang('menuenglish')); ?>"->build_menu('1'); ?>
i know the uper code is wrong but for makeing it clear..
instead of the dynamic_menu i wanto to echo from my language varaiables
one of my language variable inside the dymanic menu
regards
Just do this :
<?php
$menu = lanchor($uri, lang('menuenglish'));
echo $this->{(string) $menu}->build_menu('1');
?>
But if you search for this in Google, you will be able to find the answer.
