I am having two problems, one of them odd and the other confusing.

Firstly I have basically the same code in two pages and in one page it works and in the other it comes up with an error.

   echo "<td style='width: 800px'>" . '<img height="100" width="100" src="data:image/jpeg;base64,'.base64_encode( $row[photo] ).'" >' . "</td>";

This comes up with the error Use of undefined constant photo - assumed 'photo'. Which to me means syntax error but for the life of me I cannot work out what needs to be done.php/html syntax can absolutely baffle the hell out of me.

The second problem is just an odd problem.

a:link {
  color: black;
}

Links are black.

a:hover {
  color: #4cff00 ;
}

links turn green when the mouse is hovered on them.

a:visited  {
color:black;
}

Links are no longer green when hovered over but instead are always black. I would like them to be green when hovered over but black at every other time, I cannot seem to get this.

  • because php is parse it as a constant. since, there are no constant like `photo` this error message will appear what OP show us. – vaso123 Nov 03 '14 at 11:36

Use $row["photo"] for your first problem. Add quotes or double quetes around your key photo, because if not, php parse as a constant.

For your css problem:

a:link, a:active, a:visited {color: #000}
a:hover {color: #4cff00;}

You need to set all other cases to black with pesudo codes.

  • Thank you very much, I do not understand when which quotations should be used, sometimes " sometimes ' sometimes ` or sometimes a combination of them. Thank you though. – Murphy Nov 03 '14 at 11:35
  • Alternatively, just use `a:hover {color:#4cff00 !important;}`. "It'll do." – Dave Salomon Nov 03 '14 at 11:37

base64_encode( $row["photo"] );
