I am trying to use an image as a button to refresh pages on a website. The footer (a php include) is currently using this code to refresh each page:
<img src="/images/refresh.png">
which of course works. BUT I would like to improve it. Essentially, it would be something like this:
onClick="javascript: window.location.href='abcd.html';"
BUT I need it to work dynamically because I'm using php pages. So I was thinking this would work:
<img src="/images/refresh.png">
But it doesn't work. Any ideas? I'm using <? php $_SERVER['REQUEST_URI'] ?> wrong (obviously), so, any ideas for assistance? Thank you for any help!
Problem noticed is you have a space between <? and php in the following line:
<img src="/images/refresh.png">
Also you want to echo out the value for $_SERVER['REQUEST_URI']. You are just calling $_SERVER['REQUEST_URI']. Also as #NickCoons pointed out when using the echo construct you need to add a semi-colon i.e. echo $_SERVER['REQUEST_URI'];.
Try the following:
<img src="/images/refresh.png">

I'm struggling with the syntax of this:
echo '<strong>Datasheet</strong>';
The central PHP element gets a URL from a WooCommerce custom field (I know this works ok on its own). That needs to be turned into a viable link opening a new page, and the whole sits in a PHP wrapper on the page.
Where am I going wrong?
Try this hopefully, it will work.
echo '<strong>Datasheet</strong>';
Try adding more to / changing the href
something like this might work
echo '<strong>Datasheet</strong>';
You'll have to adjust a little bit, but should do the trick

I'm trying to create a facebook share button in each of my post, and the share content will be dynamic, which mean I will be able to customize its thumbnail, title and description for each of the post.
below is the code that I use(I'm using advance custom field plugin in wordpress by the way):
<a onClick="window.open('http://www.facebook.com/sharer.php?s=100&p[title]=<?php the_field(videotitle); ?>&p[summary]=<?php the_field(video_description); ?>&p[url]=<?php echo get_permalink(); ?>&p[images][0]=http://img.youtube.com/vi/<?php the_field(youtube_thumb); ?>/maxresdefault.jpg','sharer','toolbar=0,status=0,width=548,height=325');" href="javascript: void(0)" rel="nofollow"></a>
///////////////////////////////////////////////////////////////////////////////////////////////////////
Below is the php that will echo out my content from my CMS:
<?php the_field(videotitle); ?>
<?php the_field(video_description); ?>
<?php echo get_permalink(); ?>
The code works fine, but I noticed when I enter the the title/description too long or use special characters in my post the button stop working.
How should I overcome this? I'm still very new to php, please explain in layman's term if possible and thank you in advance.
The problem is most likely caused by passing in unescaped special characters into a direct javascript call.
Right now, you have the following javascript executing when the link is clicked:
window.open('http://www.facebook.com/sharer.php?s=100&p[title]=<?php the_field(videotitle); ?>&p[summary]=<?php the_field(video_description); ?>&p[url]=<?php echo get_permalink(); ?>&p[images][0]=http://img.youtube.com/vi/<?php the_field(youtube_thumb); ?>/maxresdefault.jpg','sharer','toolbar=0,status=0,width=548,height=325');
You are passing in several PHP variables, which may alter the format of your javascript. For example, let's say the_field(videotitle); returns Maria's Video. If you note, your string has a quote in it due to Maria's.
Now, you if pass this title into your javascript, you're going to have an un-escaped quote, causing a JS error, because it will output like this:
... [title]=Maria's Video ...
To address this, you must format out PHP output to ensure that it will not affect the JS code. In my example, you can encode the outputted strings using the urlencode function included with PHP, like this:
<?php urlencode(get_the_field(videotitle)); ?>
Just remember that passing PHP variables into javascript CAN alter the syntax of your javascript function. If the final javascript function contains syntax errors caused by the PHP output, it will not run.
You can see the javascript errors on the page you are debugging by hitting F12 in your browser and viewing the Console tab.
I'm trying to build a custom top toolbar which an iframe below it.
Something similar to this:
http://themes.goodlayers.com/?theme=greenearth
I plan one using it on a blog, so i will be making posts linking to other sites. My question is what do i need to make a custom url function that so i just add it in front of the other site's url so that it shows up in an iframe.
For example:
I want to link to google in an iframe with my top toolbar above.
Is there a script that allows me to use a url like this:
http://www.mywebsite.com/frame.php?http://www.google.com/
Thanks for your time!
Iframes are always bad. Don't do it.
That said, with PHP, you can do this:
<iframe src="<? echo $_SERVER['QUERY_STRING'] ?>" />
You can also do something like mywebsite.com?url=google.com, and use $_GET['url'] instead.
Eg url: http://mywebsite.com/index.php?iframe=http://www.google.ro
PHP:
<?php
if ($_GET['iframe']) {
echo"<iframe src='".$_GET['iframe']"' width='200px' height='150px'>";
} ?>
I hope this will help you!
Hello I am trying to figure out how to make it so when someone clicks a link on my search results it will open in a new window and in the new window have an iframe that displays the url. I am not sure how to go about doing this. I have
$row['url']
that displays the url for each result to use.
To be more specific I am trying to do what filestube does. I like the feature a lot and would like to use something like it on my site. Here is an example url to show you want I mean http://www.filestube.com/5a4c10249bd9fce003e9/go.html
when the link is clicked on filestube it will open a page like this. I have seen lots of sites do this but filestube is what pops in my head right now. Can anyone provide me with a code example or try to explain how to do this? thanks.
You need to redirect to a URL inside of your application, example my_url.php and post to it in parameters the URL you want to show. Than in that script, load an iFrame with that URL.
Example of my_url.php?url=http://www.google.ca:
<div>You Header</div>
<iframe src="<?php $_GET['url']"></iframe>
<div>Your Footer</div>
The link should point to another PHP page. Something like this.
http://www.google.com
In your open-link.php, write your iframe code.
<iframe src="<?=$_GET['url']?>"></iframe>
Assuming you have PHP file named external.php
Make that PHP file accept a $_GET parameter.
Pass the URL as a param
Use that URL to point the iframe in that PHP file to whatever URL is passed
