Change <td> color on condition - php

Question

Hi i have this PHP which take sql query divide it into two columns and print table. Now i need to change color of TD where value > 0. I've add color change by class. It's working but not correct. It change color of whole string but not TD cell.
$stmt=ociparse($olink, $sql);
if (!$stmt) {
$e = oci_error($olink);
trigger_error(htmlentities($e['message']), E_USER_ERROR);
}
$r =ociexecute($stmt,OCI_NO_AUTO_COMMIT);
if (!$r) {
$e = oci_error($stmt); // For oci_execute errors pass the statement handle
print htmlentities($e['message']);
print "\n<pre>\n";
print htmlentities($e['sqltext']);
printf("\n%".($e['offset']+1)."s", "^");
print "\n</pre>\n";
}
$ncols = oci_num_fields($stmt);
$cur_dt = 1;
echo "<TABLE border=\"1\" width=\"100%\" align='center' cellspacing='0' cellpadding='0' class=\"sortable\">";
/* echo "\n<tr>"; */
for ($i = 1; $i <= $ncols; $i++) {
echo "<th bgcolor=\"#2B75C1\" class=\"header\">".oci_field_name($stmt, $i)."</th>";
}
for ($i = 1; $i <= $ncols; $i++) {
echo "<th bgcolor=\"#2B75C1\" class=\"header\">".oci_field_name($stmt, $i)."</th>";
}
$str=1;
while (oci_fetch($stmt)) {
if ($str % 2 == 1)
{
echo "\n";
echo "<tr";
$hrr="";
echo ">";
}
for ($i = 1; $i <= $ncols; $i++) {
echo "<td";
echo $hrr;
if (oci_result($stmt, 2) >= $cur_dt) {$hrr= " class=\"hour\"";echo $hrr;}
echo ">";
echo oci_result($stmt, $i);
}
echo "</td>";
if ($str % 2 == 0) {echo "</tr> \n";}
$str++;
}
echo "</TABLE>";
oci_close($olink);
?>
</div>
</body>
</html>
0 in second column should be blue, but it ged "hour" class and change color

Answer 1

create a class in your css file like .change{background-color:green} in your
<td>
for ($i = 1; $i <= $ncols; $i++) {
$hrr ="";
if (oci_result($stmt, 2) >= $cur_dt) {$hrr = 'class="change"';}
echo "<td ".$hrr.">";
echo oci_result($stmt, $i);
}
echo "</td>";
if ($str % 2 == 0) {echo "</tr> \n";}
$str++;
}

Answer 2

Use css to style a single cell style="background-color: #2B75C1;"
If you want to change the color of the string style="color: #2B75C1;"
echo '<th style="background-color: #2B75C1;" class=\"header\">'.oci_field_name($stmt, $i).'</th>';

Answer 3

Replace
echo "<td";
echo $hrr;
if (oci_result($stmt, 2) >= $cur_dt) {$hrr= " class=\"hour\"";echo $hrr;}
echo ">";
echo oci_result($stmt, $i);
}
echo "</td>";
For
echo '<td' . (oci_result($stmt, 2) >= $cur_dt ? ' class="hour"' : '') . '>';
// ^ shouldn't be there '$i'?
echo oci_result($stmt, $i);
echo '</td>'; // closing tag for <td> in optional, you can remove that to make your HTML more readable.
// remove $hrr variable, you don't need it.

Answer 4

I think, you have to replace the "2" with $i . Replace the following code
if (oci_result($stmt, 2) >= $cur_dt)
With the solution.
Solution 1 :
if (oci_result($stmt, $i ) >= $cur_dt)
Solution 2 :
if ( (oci_result($stmt, $i ) >= $cur_dt) || oci_result($stmt, $i ) > 0)
