variables in img src

this is going to an easy one i think but for the life of me i cant get it to work.

i have a variables $id i want to put it in a img src that i have echo (eg. "uploaded/$id.jpg")

i have tried lots of way and looked all over the net and cant get it to work

echo "

            <td>

            </td>

 ";

this is what the echo looks like if anyone can tell me why it is not work would be a big help

It's because you're mixing your double quotes with single quotes and you forgot the . concat operator after $id. Try this:

echo '

        <td>
         <img src="uploaded/'.$id.'.jpg">
        </td>

';

No one stated the obvious:

Separate HTML and PHP, don't echo HTML:

<td>
    <img src="uploaded/<?php echo $id; ?>.jpg">
</td>

You are mixing single and double quotes. Try this:

echo "<td>
<img src='uploaded/{$id}.jpg' />
</td>";

You're using double quotes inside a double quoted string.

 echo "<td>
 <img src='uploaded{$id}.jpg'>
 </td>
 ";

Your mixing of quote styles is the problem. This should work.

or

echo "<td>
<img src=\"uploaded{$id}.jpg\">
</td>
";

Try this:

echo "<td>
    <img src=\"uploaded/{$id}.jpg\">
</td>";

EDIT: I think you were missing a / in the image path. Is "uploaded" a directory?

You were mixing single and double quotes. Double quotes allow you to embed variable in them like this... "Hello, $name" but if you tried "name$firstBlue", PHP would assume you were trying to insert the value of $firstBlue. You'd have to use "name{$first}Blue" for that to work. Always placing variables in {curly braces} is a good habit, because it prevents silly mistakes.

why it is not working.

 echo "//double quotes begins here

                <td>
                 <img src="/*it will end here later portion will not be printed*/ uploaded'.$id'.jpg">
                </td>
 ";

you can use

echo '<td>
         <img src="uploaded/'.$id.'.jpg">
        </td>
';
