Hi im using smarty and have declared variables which basically are meant to output the following code.
<img src="/images/port.png">
However when this is what it outputs <img src="/images/port.png">
The HTML tags are not working and it just shows text.
The code i used in my PHP file is {$configoption.optionname}
Any help would be great.
I'm not very active, my reputation isn't high enough to comment, but everyone will ask you to see more of your code. If you can put it up I can edit this answer with more helpful info.
Is there a reason you can't just set your smarty variable to the inner string "img src='/images/port.png'" and put content into your template like so
< {$imgStr} > if brackets are giving you trouble?

If I execute
print_r('Hello');
on a Wordpress code snippet, where would this actually print? I'm using Safari.
print_r in php typically prints in the parent node of the node you placed the code within.
Since you didnt give more information i assume that
this is the php print_r.
So its most likely that the output will be in the middle of your HTML code or your snippet.
You should find it in the HTML source and maybe also see it on the website
pretty new to Mysql, HTML and PHP and I can't seem to find much information on this trouble i'm having.
I Am making my own rough project manager type thing and I have a form that lets me change the contents of each individual change log, the problem I have however is that when I load the data in to the text area it start with a big indentation at the start, like 3-4 tabs inwards. I would attach an image but I need at least 10 rep to do that.
Basically, it feels like the data in the database has tabs or something at the start of it, but when I go to look in PHPmyadmin at the field, it just looks like it should do, not tabbed at all.
I've tried using strip_tags() but I think it only works on visible tags.
Does any1 know how to get rid of this or what is causing the problem?
I'll be following this question closely to see if anybody can provide an answer because I'm stumped.
Thanks,
Try to echo your php code with no blanks :
Possible tabs, bad example :
<textarea>
<?php echo $tabContent; ?>
</textarea>
Avoiding tabs :
<textarea><?php echo $tabContent; ?></textarea>
You can also try to trim your php content like that :
<textarea><?php echo trim($tabContent); ?></textarea>
Try doing var_dump and look how long your queried string is.
If it is as long as in your database you problem is within the textarea.
Is there any css you use with textarea?
Thanks so much to everyone who commented and answered this, The problem was missing a double quote from a div higher up on the page! Embarrassing, but again thanks for your efforts! for the record, my problem was that higher up on the page, there was a div like this: directly before I inserted my dynamic div.
I have a pretty simple problem, but I haven't been able to dig up any info on why it's happening.
basically I'm using php to echo quite a bit of html, about 6 divs. one div in particular always displays wrong when viewed on the browser. I'm using notepad++ encoding UTF-8 without BOM. here is an example:
in my index.php, I write:
<? echo '<div class="DivButton">Logout</div>'; ?>
all I see is the text 'Logout' without CSS. when I view the code in a browser it looks like this:
<div class=" divbutton">Logout</div>
Another clue is that often there are 1 or 2 lines before the class, for example in the browser:
<div style="background:#000; left:0px;">Welcome to your website</div><div style="
divbutton">Logout</div>
and ideas are greatly appreciated
As mentioned above, there is no way from the code provided that whitespace can be generated unless you put it there without intention, HTML ignores white spaces anyway so there shouldn't really be such an issue. The case on the code you provided and the output do not match either? Are these actual snippets or just from what you have wrote here.
<div class="divbutton"><? echo 'Logout'; ?></div>
Try less echo, keep it simple so you can see that you are just echoing the 'Logout', I assume you will want this to be dynamic Login / Logout depending on whether there is a session.
I'm looking for something that Is really hard for me to do.. I really tried to search all over the net for Solution, But I couldn't seem to find any. I also tried doing this for hours.
What I'm doing: Making a theme for PHPBB2, Installed a MOD that can include PHP in themes.
What is the problem: When I'm doing {} tags in php, It just can't echo those tags.
Let's say I have a function that creates a Table for me, like that:
CreateMyTable(Name,Size,Color);
I put in the function those strings:
CreateMyTable("{FORUM_NAME}",1000,red);
The title stays blank, I actually want it to echo {FORUM_NAME}.
How can I do this?
P.S: I can't do this
CreateMyTable(?>{FORUM_NAME}<?php , 1000, red);
It's not going to work becuase <? = <!-- PHP --> , ?> = <!-- ENDPHP -->.
Thanks for your help :)
If you look in the PHPbb2 template class, you'll find that the template is simply an evaluated set of PHP using the eval() function. You can either print the contents of the PHP before it is parsed using eval() and then use the variable name that the template gives, IE something like (which may not work depending how your template is setup):
CreateMyTable(((isset($this->_tpldata['.'][0]['FORUM_NAME'])) ? $this->_tpldata['.'][0]['FORUM_NAME'] : '' ),1000,randomcolor());
Please note, in order to do it similar to the way above you'd actually have to insert this into your template class.
An much better solution is to avoid using the mod that allows PHP in templates and use JavaScript in the templates to create the function, then print a call to that JavaScript function.
This will work:
CreateMyTable(FORUM_NAME,1000,red);
I also noticed that red is used without quotes - is this also a constant? If it's a variable it needs to have a $ in front of it. If it's a string it should be between quotes.
CreateMyTable(FORUM_NAME,1000,"red");
I want to display html code just like what your see here.
<textarea><script id="ff">gdgdgs</script></textarea>
and have it displayed without altering the page. and have it nicely within a box like this.
How is this achieved?
I think the best way is to actually have a look and see how Stackoverflow does it! :)
If you right click on your code box in Chrome and select inspect element, it'll show you the markup for that box. It's so useful to be able to do this, obviously not to rip people off, but learn how other people put websites together, and how they achieve cool effects like code boxes! :)
Interestingly enough though, if you simply right click on the page and go to view source, you'll see something slightly different:
<pre><code><textarea><script id="ff">gdgdgs</script></textarea>
</code></pre>
So we can see here that this is what the mark-up for that box looks like before the page has loaded and any JavaScript is run. When the page starts to load on the client side, some JavaScript will be run which takes the above mark-up and tranforms it to look like the mark up you see when you right click on the code box and inspect it in chrome. Doing this gives you a real-time view of the HTML on the page:
<pre class="lang-php prettyprint">
<code>
<span class="tag"><textarea><script</span>
<span class="pln"></span>
<span class="atn">id</span>
<span class="pun">=</span>
<span class="atv">"ff"</span>
<span class="tag">></span>
<span class="pln">gdgdgs</span>
<span class="tag"></script></textarea></span>
<span class="pln"><br></span>
</code>
</pre>
So if you have a look, you can see the transformed code uses a pre tag. This basically says, anything between here you can treat as a literal or in otherwords, keep line breaks and spaces where I left them!
As well as using the pre tag to wrap the code, you can also see that they use different CSS classes. This is to achieve the color coding you can see.
They also use a code tag which as far as I can see, is very similar to pre, only it makes your markup a bit clearer by saying, within this tag, you should expect to see code. It's probably more semantic more than anything, like the HTML tag artical. In most browsers, it'll also change the font for text inside the code tag to mono-space, which is a bit more code like! :)
You can go furhter into this and see exactly what their CSS classes look like, from this you can start to build a mental picture to see how their mark-up and CSS works together to product their nice code boxes.
Of course, if you don't want to roll this functionality yourself, you can use someone elses framework to achive this. SyntaxHighlighter for example if widely used and recommended.
With Syntax Highlighter, you simply reference the Syntax Highlighter CSS and javascript, and then only need to wrap your code in one pre tag to get it working, something like below:
<pre class="brush: xml">
<textarea><script id="ff">gdgdgs</script></textarea>
</pre>
It might be worth a look!
Hope this helps! :)

This website here can help you with your particular problem. It converts your tags/html/javascript to ASCII. If you need a function, here it is. It converts the passed tags/html/javascript to ASCII. The ASCII code is escaped and treated as text by the browser. You can latter use the generated ASCII and add it to the box.
function stringToAscii(s)
{
var ascii="";
if(s.length>0)
for(i=0; i<s.length; i++)
{
var c = ""+s.charCodeAt(i);
while(c.length < 3)
c = "0"+c;
ascii += c;
}
return(ascii);
}
Use the Encoded Version like this:
<textarea>
<script id="ff">
gdgdgs
</script>
</textarea>
Is this what you mean?
<textarea><script id="ff">gdgdgs</script></textarea>
Look up HTML entities.
Yeah, just include it like:
$(document).ready(function(){
var a = '<textarea><script id="ff">gdgdgs</scrip'+'t></textarea>';
$("div").css('background','red').text(a);
});
I use the <xmp> element.
