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 have created a custom wordpress post type everything works but my client asked me to insert a function that doenst show the button if the link field is empty that is also working but when I want to display the tekst or link the part where the php is inserted just doesnt shows up what am I doing wrong
I am able to get the data on other parts of this php file but not in this part of the page
<?php
$linktitle = $day_aray=get_field("under_shoe_button_title");
$linkexist = get_field("under_shoe_button_link");
echo($linktitle);
if (empty($linkexist)) {
echo '<html> <p></p></html>' ;
}
else {
echo '<html>
<a href="google.nl" class="button primary is-bevel box-shadow-3 box-shadow-4-hover expand" style="border-radius:5px;"
</html> <?php echo($linktitle); ?> <html><span></span>
<i class="icon-shopping-cart"></i></a>
</html>';
}
?>
If you would look carefully, you would notice, that you are echoing a string where, inside the string, you are trying to echo again. Even with little programming knowledge, you should understand, that it is not logical to do that.
The same goes for php opening <?php tag. You opened the tag at start of the page and later on, inside a string, you are trying to open it again. This does not work.
Instead, close the string (or escape it) and then add the echo option.
echo '<html>
<a href="google.nl" class="button primary is-bevel box-shadow-3 box-shadow-4-hover expand" style="border-radius:5px;"
</html>';
echo($linktitle);
echo '<html><span></span>
<i class="icon-shopping-cart"></i></a>
</html>';
And please, read the comments to you question and learn basic HTML
There are so many things wrong in your code
Firstly you are using echo inside echo you should use concatenation instead.
so you want to echo it like this
echo '<your html code>'.$linktitle.'<your other html code>';
Also your html code is wrong coz u are using many html tags.
I am a beginner and somehow made to get the query (php & Mysql) I want and using echo i got the output as few lines without difficulty. But now I want the output inside the cell of a table. I tried something like this:
This does not work:
<tr>
<th>subject</th>
<th>grade</th>
</tr>";
echo "<tr>";
echo "<td>".$Row['name1']."</td>;
echo "<td>".$Row['subject1'].</td>";
echo "</tr>";
echo "</table>";
Whereas this work:
echo $line['name1']."<tr></td>"."";
echo $line['subject1']."<tr></td>"."";
The echo $line statement echoes the value of name1 and subject1 without any difficulty. but the echo Row is not showing the output. As my data has only one row I dont have to use any loop. I actually want two fields in first row (name1 and subject1) and then in next row the fields of name2 and subject2 and till name7, subject7. It looks like the format inside the table is wrong. Could someone help me plz?
First of all replace
echo "<td>".$Row['name1']."</td>;
with
echo "<td>".$Row['name1']."</td>";
you are missing (") at the end before (;)
Updated with the missing table tag. Try this
<?php
echo '<table>';
echo '<tr>';
echo '<th>subject</th>';
echo '<th>grade</th>';
echo '</tr>';
echo "<tr>";
echo "<td>".$Row['name1']."</td>";
echo "<td>".$Row['subject1']."</td>";
echo "</tr>";
echo "</table>";
?>
Just to expand the current answers, I'd suggest you use a single echo and concatenate the strings or even better, just use one single string and concatenate only the necessary variables:
<?php
echo '
<table>
<tr>
<th>subject</th>
<th>grade</th>
</tr>
<tr>
<td>'.$Row['name1'].'</td>
<td>'.$Row['subject1'].'</td>
</tr>
</table>';
?>
This of course works better if the amount of PHP code is greater than the amount of HTML code. But if you were to write more HTML than PHP, it'd make more sense to just open and close <?php?> tags and echoing the variable you want.
I used an answer instead of a comment for the sake of the example. Feel free to try this approach when you are dealing with several html elements and need to insert your values within them.
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...
http://i.snag.gy/BbMqx.jpg
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 $row.
It's not just for <strong tags. You can use <h1>, <p>, <div> -- it doesn't matter. PHP will output the variable content in the location you specify.
Hope this helps!
Can you check the HTML source of the output? Is the HTML still around? It looks like strip_tags() or HTMLPurifier removes your HTML. Otherwise you would either see the formatting applied or the tags in the output.
If you have HTML code in your database you don't have to do anything with it in PHP, but can directly print it.
<?php
for($i=0;$i<=100;$i++)
{
?> // why this
<tr>
<td> <?php echo $i; ?></td>
<td><?php echo "tên sách $i"; ?></td>
<td><?php echo "noi dung sach $i";?></td>
</tr>
<?php
}
?>
So that is the scenario I'm looking to understand. Thanks
The <?php opens a php script sequence so it is saying that inside this is php code. ?> closes that sequence and says that I am not longer using php code.
In your case the php opens up and starts a for loop. Inside of the for loop a table is made but it is done using html not php. Then in each table piece, php is being used to echo (write something to the screen) some content into the table. Then finally at the end the php for loop must be finished with a closed bracket. I hope that makes sense.
The meaning of that syntax, is essentially telling the server to stop processing PHP. What follows in the page, is HTML code. That is <?php tells the server process this as PHP script and the ?> says stop processing PHP script.
Normally, you'll not see HTML outputted in this manner, but instead using PHP's echo to write the HTML
<?php
for($i=0;$i<=100;$i++)
{
echo "
<tr>
<td>{$i}</td>
<td>\"tên sách {$i}\"</td>
<td>\"noi dung sach {$i}\"</td>
</tr>
";
}
?>
?> is the end tag of PHP much like </td> is an end tag of a table cell.
The PHP parser lets you enable and disable parsing by including the PHP start and end tags <?php and ?> in your document. These two samples have the same output:
One
-------------------
echo '<td>' . $foo . '</td>';
Two
-------------------
?>
<td><?php echo $foo; ?></td>
<?php
As far as which is easier to read, well, that's a matter of preference I suppose.
See also: the shortcut tag <?= for echoing a value.
You can come in and out of php execution any time you like. If text is not between php tags, it will be output rather than executed.
<?php // start executing
if($test){ ?> <!-- start a php if statement -->
<p>This will only be output if the php test is true</p>
<?php } ?> <!-- don't forget to close the if statement -->
<p>This will always be output</p>
PHP allows you to min PHP code and HTML markup in the same file, so it needs a way to tell them apart.
If you don't enclose your PHP code between <?php and ?>, it won't be processed, and will be output as HTML.
You should read a minimum of documentation before start a project (and ask basic questions).
First part (l.1 to 4) is PHP code, here you start a for loop.
Second part (l.5 to 9) is HTML code, which is include in the loop.
Third and last part is here to close the loop.
You can do the same with :
<?php
for($i=0;$i<=100;$i++)
{
echo "<tr>";
echo "<td>".$i."</td>";
echo "<td>tên sách".$i."</td>";
echo "<td>noi dung sach".$i."</td>";
echo "</tr>";
}
?>
This is a way to embed the HTML code without having to use the php print or echo function. using
?>
Another way to get at the same result would be this:
";
echo " $i ";
echo " tên sách $i ";
echo " noi dung sach $i ";
echo "";
}
?>
I want to grab data from a mysql database by using php. The data looks something like this:
apple 3
orange 2
banana 4
I want to take the data and put it in a html table and use css to make it look pretty, but I dont want to deal with it inside <?php ?>
After I grab the
$result = mysql_query("SELECT * FROM Table");
can I reference the result variable outside the <? php ?> tags?
No. PHP can only be done in <?php ... ?> or <?= ... ?>. Use a template engine such as Smarty if you want substitution in this manner.
in short, no you cant, it is a php variable (technically a resource in this case) so you have to parse it through the php engine, which requires the php tags
echo '<table>';
while ($row = mysql_fetch_assoc($result)) {
echo '<tr><td>'.$row['fruit'].'</td><td>'.$row['id'].'</td></tr>';
}
echo '</table>';
Short answer is no. HTML cannot deal with dynamic content.
If you want to cut down the amount of echo statements within your code you can store the html within a given variable and then make reference to it.
I find it better to do the following:
<table>
<?php foreach($result as $row): ?>
<tr>
<td><?php echo $row['fruit']?></td>
<td><?php echo $row['id']?></td>
</tr>
<?php endforeach; ?>
</table>
This provides clarity and minimizes concatenation.
