Echoing out variable in a table cell doesn't work

[makamo66]

When I echo out my variable in the php file it works fine but when I put the variable in a table cell it doesn't echo out.

Sounds like you're not doing it correctly.

[NotSunfighter]

You need to post your code

Thanks for letting us know.

i'm going with the answer 42.

What exactly are you telling us?  An echo is an echo.  What is the problem here?   The real problem is that you aren't giving us anything to look at in order to help you.  Does that make sense to you?

<table border='1'><tr><th>Remove&nbsp;&nbsp;&nbsp;</th><th width='100'>Your Product&nbsp;&nbsp;</th><th>Quantity</th><th>Description</th><th>Price per item</th><th>Sub Total</th></tr>

<?php

echo "<form method='post' name='yourForm'>";

echo "<tr><td></td>";

echo "<td><img src=" . $thumbnail .   "/></td>";

echo "<td>" . $cart_product_quantity . "</td>";

echo "<td> " . $product . "(s)&nbsp;&nbsp;</td>";

echo "<td> \$" . $price . "</td><td> \$" . $number .  "</td></tr>";

echo "</form>";

echo "</table>";

Which variable doesn't echo out. They all do for me once I put something in them.

(BTW, You should've learnt to use code tags by now.)

[makamo66]

None of the variables echo out.

 

[ginerjm]

Have the variables been assigned any values yet?

[ginerjm]

Try running this code.  I've added an echo at the start and end to give you at least something to 'see' if it is actually running.  If it is not, then you need to find the errors.  AND get your ini file updated to allow you to turn on error checking when you need it.

<?php
echo "Script is beginning<br>";
$code=<<<heredocs
<table border='1'>
<tr>
<th>Remove&nbsp;&nbsp;&nbsp;</th>
<th width='100'>Your Product&nbsp;&nbsp;</th>
<th>Quantity</th>
<th>Description</th>
<th>Price per item</th>
<th>Sub Total</th>
</tr>
<form method='post' name='yourForm'>
<tr><td></td>
<td><img src="$thumbnail"/></td>
<td>$cart_product_quantity</td>
<td>{$product}(s)&nbsp;&nbsp;</td>
<td>${$price}</td>
<td>${$number}</td>
</tr>
</form>
</table>
heredocs;
echo $code;
echo "<br>Script finished";

When you test this and have problems, show us the code as you ran it and be sure to show us how those vars are being set!

@ginerjm those currency symbols need escaping otherwise they are interpreted as variable variables ($$price, $$number)

<td>\${$price}</td>
<td>\${$number}</td>

 

[ginerjm]

I thought the braces might address that.

[Barand]

Alas, {}s are part of the variable variable syntax

edit:

$a = 'foo';
$$a = 'bar';

echo $$a;       //--> bar
echo ${$a};     //--> bar
echo $foo;      //--> bar

ThanX ginerjm. Your code worked perfectly (except that the dollar signs needed to be escaped)

[ginerjm]

So - did you learn how to output html and php vars a little better?
