I am creating a hyperlink in foreach loop. It is working fine. When I am passing $id in URL parameter then it is not working. my link is showing http://****/test/index.php/test/view?id=**. i don't what i am doing wrong here.
foreach($list as $item)
{
$rs[]=$item['uname'];
$id=$item['uid'];
//var_dump($id); here it's printing $id value...
echo '<b> '.$item['uname'].'<br/>';
}
I want to pass $id value with hyperlink. Please suggest me.
It's of course getting printed -- your browser is just not displaying it to you since it's not being correctly parsed as HTML due to the extra " around the $id variable.
Set your header as follows:
header('Content-Type: text/plain');
and you'll see that it returns something like:
<b> FOOBAR<br/>
^ ? ^
As you can see, the issue is the extra double-quote before 55.
Change your code to:
echo '<b> <a href="/test/index.php/test/view?id=' . $id .'">'.
$item['uname'] . '</a><br/>';
Alternatively, you could also use double-quotes and enclose your variables inside {}, like so:
echo "<b> <a href=\"/test/index.php/test/view?id=$id\">{$item['uname']}
</a><br/>";
I'd use sprintf as it's cleaner.
echo sprintf('<b> %s<br/>', $id, $item['uname']);
You have another ".
Change this:
echo '<b> '.$item['uname'].'<br/>';
To this:
echo '<b> '.$item['uname'].'<br/>';
Try this:
echo "<b><a href='/test/index.php/test/view?id=$id'>$item</a></b><br/>";
This works!
And is the easiest and cleanest option. Inside of the double escaping, the simple is used for the html and through the double escaping all variables are written inside :) . Very simple.

I'm using the echo command in PHP, but I want to enter PHP code like <?php echo $variable [id_login]?>, while echoing something else out, but this does not work.
Is this possible to do, and if so, how would I do it?
echo "<script>location='member.php?&id=<?php echo $taruh[id_login] ?></script>";
You cannot use echo or open/cloce php twice like you did, you might want to try something like the line below,
echo '<script>location=member.php?id=' . $taruh[id_login] . '</script>';
after echo you can write enything you'd like, even if it's a php variable, just use single quote and dot where you need it (like I do here), as you can see, echo is only used once..
For example:
<?php
$your_variable = 'some text';
$other_variable = 'some PHP code';
echo 'I wrote: ' . $your_variable . ' and ' . $other_variable . '!';
?>
Output will be:
I wrote: some text and some PHP code!
I hope this will bring you into the right direction..
EDIT
Also important: if you use query string in URLs, the first 1 can be a ? every other part after should be a & for example see the url below
http://www.example.com/index.php?id=12345&coder=yes&country=usa
before id I used a quest sign, for all others I didn't use the quest sign...
I have this php line which works fine:
echo "<p>" . $post['message']. "</p>";
But I want to change it so it will link to my page (not to a single post). So it should look like that.
echo "<p>" . $post['message']. "</p>";
I have tried a lot many proposition gathered on different website, but each time I am getting an error.
Any idea ?
Thanks a lot!
Using single and double quotes, you avoid escaping issues. Try this:
echo '<p>'. $post['message']. '</p>';
i see that you didn't escaped from double quote that closes href attribute:
echo "<p><a href=\"https://www.facebook.com/rscmovement\" target=\"_blank\">"
I guess You have missed the back slash () before " after www.facebook.com/rscmovement.
"https://www.facebook.com/rscmovement\" "\"target=\"_blank\">" will
Confused by the title? hehe. Not sure how to explain this one, but I think my snippet of code should explain things a little easier.
This is what I'm trying to pass through the $data variable. div is displayed as it should be, but the echo statement inside (which I need) is NOT displayed.
Where am I messing up?
$data['packagename'] = '<div class="somedoodoo"> echo $row->subscription </div>';
You can just use string concatenation:
$data['packagename'] = '<div class="something">' . $row->subscription . '</div>';
you can't execute code inside a string like that, plus, it's the wrong quotes:
$data['packagename'] = <<<EOL
<div class="somedoodoo">{$row->subscription}</div>
EOL;

I have been using the following to add a dynamic link on a page I am writing, it works ok and appears how it should on the page but I cant help but think that I am going a bit backwards with the way its written as it looks messy. What is the correct way to write it, as if I put it all in one line it doesn't work ?..
echo '<a href="./customer-files/';
echo $customerID;
echo '/';
echo $filename->getFilename();
echo '">';
echo $filename->getFilename();
echo '</a>';
Try with
echo "{$filename->getFilename()}";
Here there is the documentation with a lot of examples of how to concatenate output.
I'd approach it like this:
$safe_customer_id = htmlspecialchars(urlencode($customerID));
$safe_filename = htmlspecialchars(urlencode($filename->getFilename()));
$safe_label = htmlspecialchars($filename->getFilename());
echo "$safe_label";
I would go with this:
$fn = $filename->getFilename();
$link = $customerID . '/' . $fn;
echo ''.$fn.'';
If you're using a template layer, it is even better to break out into PHP only when you need to:
<a href="./customer-files/<?php
echo $customerID . '/' . $filename->getFilename()
?>">
<?php echo $filename->getFilename() ?>
</a>
This way, your IDE will correctly highlight your HTML as well as your PHP. I've also ensured that all PHP is in single-line blobs, which is the best approach for templates (lengthy statements should be banished to a controller/script).
Concatenation is your friend. Use a . to combine multiple string expression into one.
echo ''.$filename->getFilename()/'';
Even better way would be
$filename = $filename -> getFilename(); //cache the filename
echo "<a href='/$customerId/$filename'>$filename</a>";
// ^ On this echo NOTICE that variables can be DIRECTLY placed inside Double qoutes.
I am echoing back these 2 variables in to a table, but wanted to know how to add a line break between these 2?
echo $row ['username'] . $row ['date_time'];
if you're printing an HTML output to your browser:
echo $row["username"]."<br />".$row["date_time"];
EDIT:
when printing to HTML - you better print the variables after passing them through htmlspecialchars function in order to avoid Cross-site-scripting (XSS), I'll do it this way:
echo htmlspecialchars($row["username"],ENT_QUOTES)."<br />".htmlspecialchars($row["date_time"],ENT_QUOTES);
if you want to print it to a file or something similar:
echo $row["username"]."\n".$row["date_time"];
you can always echo normal html from php.
echo "<div id=\"mydiv\"> Div content goes here </div>";
note the backslashes for double quotes wrapping mydiv to escape them.
so you can add a tag in between them to get a new line.
echo $row["username"] . "<br />" . $row["date_time"];
