My website has multiple languages, and I have a PHP line in below that it get data from sql and it shows text on page:
<?php get_footer_menu_items(3, "col-md-6 go-right","ftitle go-text-right","footerlist go-right go-text-right" );?>
The number 3 in above code is for text (About Us)
But in my page, I have another PHP echo that it show text based on selected language:
<?php echo trans('0295');?>
This above line is for text (About Us)
how can I combine these two lines together that it will change text to selected language?
get_footer_menu_items function probably takes integer as first argument and then as index in an array of some sort with text strings.
So if you call it like this:
get_footer_menu_items(trans('0295'), "col-md-6 go-right","ftitle go-text-right","footerlist go-right go-text-right" );
it won't work anyway.
Without mentioned function's code it's hard to help.

I have a multi language website. I have three php files:
lang.de.php,lang.en.php, lang.hr.php
On index page I am changing text using this line of code:
<h2><?php echo $lang['TEXT'];?></h2>
Variable TEXT has different value in every lang.php file.
Now, I want to change the name of the .pdf file the same way, but I can't get it to work. I want to do something like this:
How can I do this?
Try to remove the double quotes before and after the
Correct syntax to do this:
So I hava a problem. On client side users insert theris data in textbox, radio in textarea. All number of input is stored in hidden type, sove php script on my server side knows how many input does it has. Sometimes there is just 20 inputs, sometimes 25 or 30, so the holl stuf is daynamic.
I have two questions:
1. How on server side dynamic generate variables and use them as $input1, $input2 and os on.
2. Let's say that I have somehow managde first problem so my second question is how to make query which sometimes uses only 20 parameters, sometimes 25 and so on. I don't wanna use arrays and tables;
I stareted php code:
for($i=1;$i<=$num; $i++){ //I get num from a hidden type
${"question".$i}="j";
if(isset($_POST["${"question".$i}"])){
${"question".$i}=$_POST[${"question".$i}];
echo question1; //this doesn't work but I want make created variables
//to use like this
}
else
{
echo "You have error with reading ".$i." question";
}
}
Change echo question1; by echo $question1; (append $ symbol before your var name)
Or in dynamic way:
echo ${"question" . $i}
Why would you like to use the variables like this?
If the input is dynamic use it like an array! -> Easier and cleaner.
There is good example how to handle a dynamic array input: Post array from html to php
I'm relatively new to this and am familiar with echo in PHP but what I need is to have the contents of a field in a database to be placed in the page (but not as a written field)
For example
<?php echo $product_description['description']; ?>
the field description has html formating in it already so when I use 'echo' it writes out for example
<p>text on firstline <br> text on next line
And what I want is that this html from this field in the database that already has html formating to simply placed in the php page which would make it look like this
text on firstline text on next line
I assume I just need to use a different command than ECHO but don't know which one.
Try
echo html_entity_decode($product_description["description"]);
If that works, the HTML in your database has been encoded using htmlentities, so you must decode it to write to a page.
strip_tags is what you're after.
Use it like so: echo strip_tags($your database bit to echo here);

I am using a plugin that is generating my price value and pulling it from an array:
<?php echo __('Price: ', 'event_espresso'); ?></span> <?php echo
$org_options['currency_symbol'].$event->event_cost; ?>
I want to convert this generated value into my visitors own currency depending on the country their in with the plugin 'Worldcurrency'
However you have to input a value in the short code like so:
[worldcurrency curr="EUR" value="25"]
in united states will show:
(~30$ USD)
Now I know how to use a shortcode in a template php file but I don't know if its possible to insert my array value and currency symbol into this shortcode. Rather than using value="25" i need to use:
value="<?php echo $org_options['currency_symbol'].$event->event_cost; ?>"
Is this possible?
I'm not sure whether it's possible to use PHP code inline in a shortcode - and I suspect not, however an easy enough way to implement this would be to write a shortcode of your own that then called the other shortcode.
Your shortcode would generate the text you want (eg '[worldcurrency curr="EUR" value="25"]'), and call "do_shortcode($content)" which would then cause the other plugin to do the currency lookup for you.
You could put this in a plugin file and it would probably amount to less than 15 lines of code.
The other option is to modify the currency conversion plugin you are using to produce the output you want.
UPDATE:
I know I can use <ol> directky in the output but I remember using something like:
<?php echo $i++; ?> when I worked on a wordpress blog once. Every time I inserted that tag a number greater than the previous appeared so I basically did:
<?php echo $i++; ?> Text
<?php echo $i++; ?> Text
<?php echo $i++; ?> Text
I'm a front end guy (HTML/CSS) so please excuse this basic question. I just need to know what code in PHP I can use to number some text.
Text
Text
Text
into:
Text
Text
Text
Kind of like what <ol> does in html but in PHP.
Updated answer:
You can use a variable as you already do (the example you are posting should already work). Just initialize it using $i = 0;
Old answer:
You have a fundamental misunderstanding here. PHP is a scripting language, not a markup language. PHP does operations like connecting to data sources, calculating, making additions, changing entries in databases, and so on. PHP code, in short, is a series of commands that are executed. PHP has no design elements, tags and formatting options in itself.
PHP can (and usually does) output HTML (Where you have <ol>) to display things.
You can have an array of arbitrary data in PHP, coming from a file or data source:
$array = array("First chapter", "Second chapter", "Third chapter");
you can output this data as HTML:
echo "<ol>";
foreach ($array as $element) // Go through each array element and output an <li>
echo "<li>$element</li>";
echo "</ol>";
the result being (roughly)
<ol>
<li>First chapter</li>
<li>Second chapter</li>
<li>Third chapter</li>
</ol>
It depends on what type of file you are trying to write. Most often, PHP is writing a webpage in HTML, but not always. In HTML, if you want a numbered list, you should use an ordered list (<ol>).
If you're just writing a text file of some kind, incrementing and outputting a variable (like $i in your example) should work.
You mention Wordpress, so it's worth noting that if you worked on a Wordpress template before, you were using dozens of special functions in the Wordpress library, even though you may not have been completely aware that was what you were doing. A lot of the PHP heavy lifting is hidden and simplified for the templating engine, and if your current project is not built on that engine, you will have to do that logic yourself.
