PHP Link with two variables in a row

[CNGHL]

Hi There,

 

I am having trouble with a link, I am trying to put two variable into a single link but I cannot seem to get it to work right, the following code gives me a white screen error so its not very helpful, when doing the coding in Notebook ++ the .

.$row['ColorID']

is a different shade then the rest of the script so I am assuming I missing a semi colon or " or ' a long the way, any help would be wonderful

echo "<td width='100'><div align='center'><a href=\"Part_Color.php?PartID=".$row['PartID'].'&Color_ID=" . $row['ColorID'] . "" style="text-decoration:none;">'.$row['PartID']."<br>";

An easy way to do it is double quotes outside and all singles within, at concatenation use double quotes and a decimal point.

Or you can go through using backslashed double quotes.

echo "<td width='100'><div align='center'><a href='Part_Color.php?PartID=".$row['PartID']."&Color_ID=" . $row['ColorID'] ."' style='text-decoration:none;'>".$row['PartID']."<br />";

If you use the curly syntax you wont have to do all that variable escaping and concatenation and you will avoid the problem beginners usually have especially if your editor does not have syntax highlighting.

 

 

echo "<td width=\"100\"><div align=\"center\"><a href=\"Part_Color.php?PartID={$row['PartID']}&Color_ID={$row['ColorID']}\" style=\"text-decoration:none;><br>{$row['PartID']}<br>";?>

a slightly more dynamic slant on doing this -

// dynamically build the query string part of a url, from whatever part(s) it is made of -
$q = array();
$q['PartID'] = $row['PartID'];
$q['Color_ID'] = $row['ColorID'];
// add any other key/value pairs here....
$qs = http_build_query($q,'','&'); // build urlencoded query string, with properly encoded &
$label = htmlentities($row['PartID'],ENT_QUOTES); // use html entities on any content

// this is just the <a></a> link part of what you are outputting, which appears to be incomplete/broken in your code
echo "<a href='Part_Color.php?$qs' style='text-decoration:none;'>$label</a>";
