Incorporating php variable into url with href attribute - php

I am trying to create the necessary url from this code however it is working and I am struggling to find out why.
$linkere = $row['message'];
echo '<a href="me.php?message=<?php echo rawurlencode($linkere); ?>">'
Currently this code is producing the url: me.php?message= . But, I would like it to create the url: me.php?message=hello for example.
Thanks for helping!

You are passing $linkere to rawurlencode(). The variable is actually named $linker.
$linker = $row['message'];
echo '<a href="me.php?message=<?php echo rawurlencode($linker); ?>">'

You have alot of syntax problems here.
first, you need to use Concatenation message='.rawurlencode($linker).'"
second your variable do not exist, it should be $linker.
Second close the tag and insert the text, in this case i used Test.
$linker = $row['message'];
echo 'Test';

Can you try this,
$linker = $row['message'];
echo 'YOUR LINK TEXT HERE';

You don't need the <? ?> and echo in your echo, it should just be:
$linkere = $row['message'];
echo 'Test';
Otherwise you are turning php on and off again to echo something within an already open instance of php in which you are already echoing.

How to echo php code and use it?

<?php echo $row["html"]; ?>
Inside of the $row["html"] there's:
<?php $Site->Nav($owner); ?>
but when I echo it, it only echoes:
Nav($owner); ?>
How may I print the full and make it usable, which means that it will print the function Nav?
I've tried to replace <?php with [[// i the database, and just before echoing it, I change back with replace. But without success
I think you need to use eval function of php. See the example below.
$string = 'cup';
$name = 'coffee';
$str = 'This is a $string with my $name in it.';
echo $str. "\n";
eval("\$str = \"$str\";");
echo $str. "\n";
Might be it can help.
Use eval function. It might solve your problem like this:
<?php echo eval($row["html"]); ?>
Keep the code as is in DB as if you are writing it in PHP file but without PHP opening and closing tags i.e. <?php and ?>. I haven't checked this (as i am not sure what $Site->Nav($owner); will do) but hope it would work in this case.
If I understand correctly you are wanting to output the results of $Site->Nav($owner);
I have no idea what this is expected to output, but assuming it is a string of some kind that you wish to display (hence echo) - an example of achieving this would be calling your code and have that method return the value, so you can echo it out. Ie:
function Nav($owner){
// Do your stuff
return 'Your Desired Output';
}
Then on your page you would have
<?php echo $Site->Nav($owner); ?>
Which would echo "Your Desired Output".

Add PHP variable inside echo statement as href link address?

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>" ;

Combining variable and html inside a PHP variable

The code below is generating a result like this: http://localhost/my_website/ contact-us
$base_url="http://localhost/my_website/";
echo $link= "$base_url contact-us ";
But I am trying to get a result like this : http://localhost/my_website/contact-us
I have also tried the following code
$base_url="http://localhost/my_website/";
echo $link= "$base_url.contact-us ";
but the result is like this http://localhost/my_website/.contact-us
Could you please show me how to solve this problem?
Edit
I am very sorry, I did't clearly mention the exact problem I am facing here. I thought the above example would help my case. Actually I am trying to create a link that I will send at users email address.
My code
$base_url="http://localhost/my_website/";
$random_hash="1";
echo $link="
<a href='$base_url account/confirm_registration/$random_hash' target='_blank'>$base_url account/confirm_registration/$random_hash</a>";
But it is generating like this
http://localhost/my_website/ account/confirm_registration/1
echo $link = $base_url."contact-us";
$base_url="http://localhost/my_website/";
echo $link= $base_url."contact-us";
You just need to split it
Tested and works:
$base_url="http://localhost/my_website/";
echo $link=$base_url."contact-us";
$base_url="http://localhost/my_website/";
$link=$base_url."contact-us";
echo $link;
You need to learn about basic string concatenation: http://php.net/manual/en/language.operators.string.php
Try this:
$base_url = "http://localhost/my_website/";
$random_hash = "1";
$url_page = "account/confirm_registration/$random_hash";
$url = $base_url . $url_page;
$link = "<a href='$url'>$url</a>";
echo $link;

Passing DIV through $data variable, but with an Echo Statement in String

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;

Adding A Dynamic Link In Php

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.
