can anybody help me here please?
I am using AJAX for pagination in my application. So I am generating hyperlinks with for loop. as follow:
for($t=1; $t<=$hf; $t++)
{
if($t == $_GET['pageno'])
{
echo $t." ";
}
else
{
echo "<a id ='$t' href='javascript:void(0)' onclick='open_page('ajaxinfo.php','content'); javascript:change('$t');'>$t</a>"." ";
}
}
Above echo statement does not give call to function. But instead of this when i just write html hyperlink it works fine and I get to see page2.html, my HTML code is:
<a id="page2" href="javascript:void(0)" onclick="open_page('ajaxinfo.php','content'); javascript:change('page2');">page2</a>
I don't understand why this is so? But is there any problem in echo's quotes.
Please Help.
that because you have syntax error while building anchors. Try to use double quotes for tag attributes and escape them with backslash.
So, your ECHO should look like this:
echo "<a id =\"{$t}\" href=\"javascript:void(0)\" onclick=\"open_page('ajaxinfo.php','content'); javascript:change('{$t}');\">{$t}</a> ";
You have to have code to add the contents returned by the ajax to the page. I don't see that anywhere.

I'm writing an if statement in which a button needs to show if the cart is empty.
For this button I need to get the form key of the product for the data-url
So something like this:
Order
As mentioned above I need to wrap this button in an if statement, so something like this:
<?php
$_helper = Mage::helper('checkout/cart');
if (1 > $_helper->getItemsCount()){
echo 'Order';
}
else{
'<p>hello</p>';
}
?>
But obviously I can't have php echo within echo. Can anybody point me in the right direction of how to do this?
You don't put PHP inside HTML inside PHP. Since you're already in the context of PHP code, just concatenate the values you want to the output:
echo 'Order';
The resulting output is always just a string. You can simply build that string with whatever values you have.
You can just use string concatenation:
echo '<a href="#" data-url=".../' . Mage::getSingleton(...) . '"' ...
Simply don't open PHP up again. You can terminate the HTML interpretation inside an echo.
Your code should look like this:
<?php
$_helper = Mage::helper('checkout/cart');
if (1 > $_helper->getItemsCount()) {
echo 'Order';
}
else {
'<p>hello</p>';
}
?>
Hello dear programmers,
I have a problem with the echoing of a html phrase with an onclick function that executes a javascript function. I want to build a tabpage, for a image gallery.
The echo:
echo "<div class='albumitem'><a class='tablinks' onclick='openAlbum(event, '".$album."')'><h1 class='galleryheader'>".$album."</h1></a><div id='".$album."' class='tabcontent'>";
Everything goes well, except the passing of the variable in the onclick function, as you can see here. What actually the HTML looks like:
<a class="tablinks" onclick="openAlbum(event, " aubing')'=""><h1 class="galleryheader">Aubing</h1></a>
But this onclick event has to look like this:
onclick="openAlbum(event, 'Aubing')"
Is there a way to actually realise this or do I have to find an other option?
I actually tried switching " with ', didnt go very well....
Thank you for everybody that tries to help
Try this:
echo "<div class='albumitem'><a class='tablinks' onclick='openAlbum(event, \"$album\")'><h1 class='galleryheader'>".$album."</h1></a><div id='".$album."' class='tabcontent'>";
see escaped double quotes in the onclick definition
addslashes is what you are looking exactly.And also you have to remove the single quotes in variable.Try to do the following way.
echo "<div class='albumitem'><a class='tablinks' onclick='openAlbum(event, '".addslashes($album)."')'><h1 class='galleryheader'>".$album."</h1></a><div id=".addslashes($album)." class='tabcontent'>";
Hope this help.
An alternative:
$escapedString = htmlspecialchars('This is a test string: < > & \' " end.', ENT_COMPAT);
echo "<div onclick='alert(this.dataset.name)' data-name=\"$escapedString\">Click Me</div>";
This approach avoid quotes inside function, no quotes nesting.
I would like to redirect to other pages but the = sign isn't working, the page name, the title, and the id are coming from database. I tried putting . before the = but that doesn't work. I think this should be simple but couldn't figure it out. can someone help me out?
echo "".click here."";
Try like
echo "<a href='".$row['page']."=".$row['topic']."&id=".$row['id']."'>click here</a>";
Like this ?
echo 'click here';
You were just missing a few quotes and dots. This will work.
echo "<a href='".$row['page']."=".$row['topic']."&id=".$row['id']."'>click here</a>";
I'm trying to use a PHP variable to add a href value for a link in an echo statement.
Here's a simplified version of the code I want to use. I know that I can't just add the variable into the echo statement, but I can't seem to find an example anywhere that works.
$link_address = '#';
echo 'Link';
Try like
HTML in PHP :
echo "<a href='".$link_address."'>Link</a>";
Or even you can try like
echo "<a href='$link_address'>Link</a>";
Or you can use PHP in HTML like
PHP in HTML :
Link
you can either use
echo 'Link';
or
echo "Link';
if you use double quotes you can insert the variable into the string and it will be parsed.
Basically like this,
<?php
$link = ""; // Link goes here!
print "Link";
?>
as simple as that: echo 'Link';
You can use one and more echo statement inside href
Link
link : "/profile.php?usr=firstname&email=email"
This worked much better in my case.
HTML in PHP: Link
The safest way to generate links in PHP is to use the built-in function http_build_query(). This function is very easy to use and takes an array as an argument.
To create a dynamic link simply echo out the result of http_build_query() like so:
$data = [
'id' => $id,
'name' => $name
];
echo 'Link';
If you want to print in the tabular form with, then you can use this:
echo "<tr> <td><h3> ".$cat['id']."</h3></td><td><h3> ".$cat['title']."<h3></</td><td> <h3>".$cat['desc']."</h3></td><td><h3> ".$cat['process']."%"."<a href='taskUpdate.php' >Update</a>"."</h3></td></tr>" ;

How to get useful error messages in PHP?
Ive started on part of my new year resolution and decided to learn php, as part of it im trying to parse in an xml feed, and echo out the name of the events wrapped in <a> tags linking them back to the events page on the xml feed's site.
I think ive got it all in but i cant seem to see why this isnt working im just getting a blank page, if some one could point me in the right direction it would be much appreciated, cheers
<?php
// F1 W/H xml feed
$xml = simplexml_load_file('http://whdn.williamhill.com/pricefeed/openbet_cdn?action=template&template=getHierarchyByMarketType&classId=5&marketSort=HH&filterBIR=N');
foreach ($xml->response->williamhill->class->type as $type) {
$type_attrib = $type->attributes();
echo "<h2>".$type_attrib['name']."</h2>"; //Title - in this case f1 championship
} ?>
<ul>
<?php
foreach($type->market as $event) {
echo "<li>";
echo "<a href="$event_attributes['url']">";
echo $event_attributes['name'];
echo "</a>";
echo "</li>";
}
?>
</ul>
echo "<a href="$event_attributes['url']">";
try changing that line to
echo "<a href=\"".$event_attributes['url']."\">";
The Php parser is pretty funny about this. Usually you pick one and just stick to it, or use both single quotes and double quotes as you please. Just remember that strings with double quotes are parsed for variables.
$hello = "Hello";
echo "$hello master";
is the same as
$hello ="Hello";
echo $hello.' master';
When you are testing your PHP scripts, you'll find it useful to switch on errors - then PHP will actually tell you why it isn't showing you anything:
error_reporting(E_ALL);
Normally you will have missed a ; or mis-typed a variable name.
in your case the error is here:
echo "<a href="$event_attributes['url']">";
You have accidentally ended the string with a double quote, so PHP thinks the string ends here:
echo "<a href="
This is where using single-quotes can be very handy because your double quotes won't then close the string.
echo '<a href="' . $event_attributes['url'] . '">';
The main difference between single and double quotes in PHP is that double quotes has special clever parsing rules and single quotes doesn't. For example:
$myVar = "BLAH";
echo "Example $myVar"; // Example BLAH
echo 'Example $myVar'; // Example $myVar
In your unordered list, you should use a dot to concatenate your string, and escape your double quotes like this:
echo "<a href=\"".$event_attributes['url']."\">";
Instead of
echo "<a href="$event_attributes['url']">";
Your example throws and error because you haven't used proper string concatenation. However, even with correct concat, it would render as <a href=http://someurl>, and you'd need to add the double quotes according to html standard. Hence you have to double quote.
if you want to not be troubled by having to switch between using a ' or a " then i suggest using the php alternative syntax php alternative syntax
with the given code it would look like
<?php
// F1 W/H xml feed
$xml = simplexml_load_file('http://whdn.williamhill.com/pricefeed/openbet_cdn?action=template&template=getHierarchyByMarketType&classId=5&marketSort=HH&filterBIR=N');
foreach ($xml->response->williamhill->class->type as $type) {
$type_attrib = $type->attributes();
echo "<h2>".$type_attrib['name']."</h2>"; //Title - in this case f1 championship
} ?>
<ul>
<?php foreach($type->market as $event):?>
<li>
<a href="<?php echo $event_attributes['url']; ?>">
<?php echo $event_attributes['name']; ?>
</a>
</li>
<? endforeach;?>
</ul>
one advantage this would bring is that it would produce cleaner code since you can clearly distiguish your php code from your html which is the presentational part at the price writing all those other <?php ?> and as what others would claim a performance degradation. the choice is yours
Change
echo "<a href="$event_attributes['url']">";
for
echo "<a href=".$event_attributes['url'].">";
You are missing the periods in your second echo, where you have your $event_attributes['url']
<?php
foreach($type->market as $event) {
echo "<li>";
echo "<a href=".$event_attributes['url'].">";
echo $event_attributes['name'];
echo "</a>";
echo "</li>";
}
?>
I would recommend you to enable your error log, it would allow you to know the line with problems in any of your scripts.
