Here is my variable that I am actually getting from my MySQL Database:
<h1>This is a H1</h1>
<p>NOT BOLD</p>
<p> </p>
<p><strong>BOLD</strong></p>
I am using TinyMCE to format the code.
Here is how I echo it
<?php
// WHILE LOOP GETTING $ROW FROM MYSQL
$conContent = $row['content'];
Then, when I go to the page, it displays the output like this...

I want the variable to make the echo formatted. So like then it will have all the html formatting.
You can insert your variable inside the <strong> tags using the following method:
<?php
/* getting row from your table */
$conContent = $row['content'];
?>
<strong> <?php echo $conContent; ?> </strong>
Another solution is:
$conContent = $row['content'];
echo "<strong>" . $conContent . "</strong";
//or echo "<strong> $conContent </strong";
If the styles are to be applied to all the rows, then you could use a foreach loop:
foreach($row as $v) {
echo "<strong>$v</strong";
}
Note: This assumes that you've the mysql array result stored in a variable called $row.
It's not just for <strong tags. You can use <h1>, <p>, <div> -- it doesn't matter. PHP will output the variable content in the location you specify.
Hope this helps!
Can you check the HTML source of the output? Is the HTML still around? It looks like strip_tags() or HTMLPurifier removes your HTML. Otherwise you would either see the formatting applied or the tags in the output.
If you have HTML code in your database you don't have to do anything with it in PHP, but can directly print it.

So I have a html table that is automatically generated after passing a query to my database. I want to create a hyperlink within my html table to a page that will pull more detailed information from a Second Table.
I was thinking of using the Tablecell creator that pulls from the First Table, and modifying so that it would encompass the table's contents with hyperlink tags. I was thinking it would look like this.
foreach(new TableRow(new AutoArrayMaker($stmt->fetchAll()) as $rowend => $row){
echo <a href = "the reusable HTML Page">;
echo $row;
echo </a>;
}
Is my idea sound from a coding standpoint?
Firstly, echo's need to be in quotation marks " So that code wouldn't fire.
There are a few ways you can output HTML. The first is using echo's:
echo "Google";
Notice how I put a back-slash before hand? This is what is known as an escape. This puts the character after into a letter depending on what it escapes to. See php docs: http://php.net/manual/en/regexp.reference.escape.php (as my description of it was poor)
The other option would be to run out of php then join back on so to speak:
<?PHP
foreach(new TableRow(new AutoArrayMaker($stmt->fetchAll()) as $rowend => $row){
?>
<a href="abc">
<?PHP echo $row; ?>
</a>
<?PHP
}
However, this is not advised.
Edit:
Also, you can make your own table very simply:
<table>
<?PHP
foreach($stmt as $row){
?>
<tr>
<td>
<a href="abc"><?PHP echo $row[id]; ?>
</td>
</tr>
<?PHP
}
?>
</table>

I currently have a php which echo my html template.
However in that HTML template there is another echo which calls from another php script.
Just wondering how do I do that? Because once I echo my html template the other it doesn't seems to echo my content from the other php script.
HTML TEMPLATE
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
CONTACT TEMPLATE
<php? $name = "hello world"; $email = "hello#world.com"; ?>
I can see what you're trying to do, and it's a simple error. You can't escape php like that whilst inside setting a variable.
Also, I must add that you are declaring php incorrectly.
This is preferred
<?php
not
<php?
So make sure for your contact template you use the correct tag.
Also to include a file you have to call it/require it.
Back to the original question - Here is your method
<php? $html = '<span>name:<?php echo $name; ?></span><span>email:<?php echo $email; ?></span>' ?>
Here is the correct method
<?php
require('contact.php');
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
echo $html;
?>
First I created the variable. And when doing so I insert the existing variables by escaping the php. Only once this final variable is created do I echo it.
Hope this helps you on your way.
Try to use include. The include statement includes and evaluates the specified file, in this case - your template.
Just Concatenation
<?
$html = '<span>name:'.$name.'</span><span>email:'.$email.'</span>';
?>
Change the tags from <php? ?> to <?php ?> in your script
I have an entry in my mysql table that contains html code:
<p>Hello!</p>
This shows up fine when I want to display it echo $entry
but when I place echo $entry in a textarea's value, it executes the code instead of showing it.
Is there any way to stop the code from executing and show the tags or convert to and from <>
Here is the code:
echo "<label for=\"details\">Details:</label><textarea id=\"details\" cols=\"60\" rows=\"10\" name=\"details\" value=\"" . $row["details"]."\"></textarea>";
Here is the entry:
<p><ol><li>HKCU/Software/Microsoft/Windows/NT/CurrentVersion/WindowsLegacy/DefaultPrinterMode<li> Set to 0 (on)</ol>
You have to escape special characters. You can do that with htmlspecialchars().
What's more, You should not set a value to the textarea but rather write it in its content:
<textarea>
<?php /* some code here */ ?>
</textarea>
i think this this will do it
<textarea><?php echo $row['details'];?></textarea>
try to save data lik
ascii_to_entities($this->input->post('ur_textara_name'));
and at the time of display
entities_to_ascii()
Here's the problem, I am trying to echo a statement or an array after dynamically generated HTML, and unfortunately the thing that i want to echo goes above the HTML, is there any way to echo it after that dynamic HTML or work around?
Code:
Link 1
Link 2
if(isset($_GET["id"]) && $_GET["id"] == "do_something") {
$html = "dynamic html generate";
echo $html;
//after this im using foreach
foreach($array as $item) { echo $item . "<br />"; }
}
As I click one of these two , dynamically generated HTML shows up. Now for example I have an array:
$array = array("error1", "error2");
All the generated PHP goes above the dynamic HTML :/.
How should i fix it so that i can echo all of this array below the dynamic HTML?
Thanks
Use buffering with ob_start
ob_start();
// dynamic html code generate
$dynamic_html = ob_get_clean();
echo $dynamic_html;
// your code
echo $dynamic_html;
Sounds like you missed some closing tags (most likely </table>) in the dynamic html. Thats why the later generated echo gets displayed at the top.
Example (Note the missing closing table):
<?php
echo "<table><tr><td>TableText</td></tr>";
echo "I should be bellow the table, but going to the top.";
?>
will produce:
I should be bellow the table, but going to the top.
TableText
I currently have the following code coming from a database table:
<h1 class="widgetHeader">My Friends</h1>
<div class="widgetRepeater">
<p class="widgetHeader">Random Selection</p>
<?php
$friends = $user->getFriends();
?>
<p class="widgetContent">
<?php
for ($i=0; $i<count($friends);$i++) {
$friend = $friends[$i];
?>
<span class="friendImage" style="text-align:center;">
<?php print $friend->username; ?>
</span>
<?php
}
?>
</p>
</div>
Now, ive tried using the eval function in php but i get a parse error unexpected '<'. I've also tried using the output buffer method (ob_start) without success too. Any ideas as to how i can get this code to evaluate without giving me an error?
note: the database code is stored in a variable called $row['code'].
The PHP eval function expects PHP code to execute as it's parameter, not HTML. Try enclosing your DB values with PHP close and open tags:
eval('?>' . $row['code'] . '<?php');
eval = evil!
Especially if the eval'd code comes from a db... one mysql injection = full php execution = full control.
Rather use some placeholders and replace them (like any other good templating system does).
You could store this in your database:
<h1 class="widgetHeader">My Friends</h1>
<div class="widgetRepeater">
<p class="widgetHeader">Random Selection</p>
{%friendstemplate%}
</div>
Then str_replace the placeholders with the content they should have. In your example i would also add a subtemplate per friend like this:
<span class="friendImage" style="text-align:center;">
{%username%}
</span>
... which you could loop and insert into {%friendstemplate%}.
You cant use eval on markup code. Either save the code to a temporary file so that you can include it, or rewrite the code so that it's not markup, something like:
print "<h1 class=\"widgetHeader\">My Friends</h1>";
print "<div class=\"widgetRepeater\">";
print "<p class=\"widgetHeader\">Random Selection</p>";
$friends = $user->getFriends();
print "<p class=\"widgetContent\">";
for ($i=0; $i<count($friends);$i++) {
$friend = $friends[$i];
print "<span class=\"friendImage\" style=\"text-align:center;\">";
print $friend->username;
print "</span>";
}
print "</p>";
print "</div>";
