PHP show image based on value in mysql Database and the image folder #raspberrypi

You missed all "" around tag values. Use this:

echo "<img class='polaroid'  height='70' src='../images/drivers/".SUBSTR($_SESSION['Driver1'],0,4).".jpg' />";

apologies i pasted a bit of code:  

whole code does have "" around
here is full code

echo "<h3><span>Your Team Name is :<b> " . $_SESSION['TeamName']. "</span> </h3>    " . 	"</b> Your choice of drivers are <b> " . substr($_SESSION['Driver1'] ,4).  "  </b>and <b>" . SUBSTR($_SESSION['Driver2'],4) .  " ,</b><p>  <img class=polaroid  height=70 src=../images/drivers/".SUBSTR($_SESSION['Driver1'],0,4).".jpg/><img class=polaroid height=80 src=/images/drivers/".SUBSTR($_SESSION['Driver2'], 0,4).".jpg  caption ".$_SESSION['Driver2'] ." <br /> <p>".

Select allOpen in new window

echo "<h3><span>Your Team Name is :<b> " . $_SESSION['TeamName']. "</span> </h3>    " .       "</b> Your choice of drivers are <b> " . substr($_SESSION['Driver1'] ,4).  "  </b>and <b>" . SUBSTR($_SESSION['Driver2'],4) .  " ,</b><p>  <img class=polaroid  height=70 src=../images/drivers/".SUBSTR($_SESSION['Driver1'],0,4).".jpg/><img class=polaroid height=80 src=/images/drivers/".SUBSTR($_SESSION['Driver2'], 0,4).".jpg  caption ".$_SESSION['Driver2'] ." <br /> <p>".

If $_SESSION['Driver1'] is "3   Nico ROSBERG" you have to use

substr(trim($_SESSION['Driver1']), 0, 1)

This code snippet appears to have a PHP parse error in it.

Please do this for us: Print out the contents of $_SESSION.  Use var_dump() to print it.  Post that information here.  Once we see the data we can give you the exact code you need to create the HTML document.

plus here is var_dump()

array(12) { ["TeamName"]=> string(8) "cs97jjm3" ["Email"]=> string(12) "ja@shdjs.com" ["FullName"]=> string(9) "jkasjkdjk" ["Driver1"]=> string(21) " 1 Lewis HAMILTON " ["Driver2"]=> string(18) " 3 Nico ROSBERG " ["Team1"]=> string(14) " 131 Mercedes " ["LewisEndofyearPosition"]=> string(1) "1" ["Team2"]=> string(15) " 9 Red Bull " ["Total"]=> string(12) "131 Mercedes" ["Password"]=> string(32) "b1a273f615207e00970cfb5d1e9a800d" ["MyProducts"]=> string(2) "14" ["submissionID"]=> string(1) "7" }

Thanks and apologies for not post full code originally

Thanks with explanation i understood problem:

You're welcome!

PHP functions are not case sensitive.  PHP variables, object property names, and array indexes are case-sensitive.

@Ray: thank you. I was sure everything was case-sensitive! Or better, I never dedicated a thought to that: I just always wrote in lowercase... And when I saw that SUBSTR and your comment about parse errors I thought you were talking about that, without noticing the missing param for 2 substr calls.
Well, another piece of knowledge in my pocket :-)
Cheers
