Highlight first row in php while loop - php

Question

I'm getting all rows from mysql database. Now I want to highlight only first row in php while loop with class name keywordHighlight.
How do I highlight only first row in php while loop result ?
if($numSearch > 0){
echo "<font color='green'>We found $numSearch result(s).</font>";
echo "<table width='100%' cellpadding='0' cellspacing='0'>";
echo "<thead>";
echo "<tr>";
echo "<td class='' valign='top' width='200'></td>";
echo "<td class='' valign='top' width='125'></td>";
echo "<td class='' valign='top' width='125'></td>";
echo "<td class='' valign='top' width='125'></td>";
echo "<td class='' valign='top' width='125'></td>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
while($resGetSearch = mysql_fetch_array($getSearch)){
$SearchCdid = $resGetSearch['cdid'];
$SearchFamilyName = $resGetSearch['family_name'];
$SearchGivenName = $resGetSearch['given_name'];
$SearchCompamyCid = $resGetSearch['cid'];
$SearchDepartment = $resGetSearch['department'];
$SearchTitle = $resGetSearch['title'];
$SearchComapnyName = mysql_query("SELECT company_name FROM company WHERE cid = '$SearchCompamyCid' ");
$resSearchCompanyName = mysql_fetch_array($SearchComapnyName);
$companyName = $resSearchCompanyName['company_name'];
if (strlen($companyName) >= 20) {
$companyName = substr($companyName, 0, 10). "" . substr($companyName, -5);
}else{
$companyName = $companyName;
}
// my Highlighted class = keywordHighlight";
echo "<tr onclick='getDetails($SearchCdid);' >";
echo "<td valign='top' >$companyName</td>";
echo "<td valign='top'>$SearchFamilyName</td>";
echo "<td valign='top'>$SearchGivenName</td>";
echo "<td valign='top'>$SearchDepartment</td>";
echo "<td valign='top'>$SearchTitle</td>";
echo "</td>";
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
echo "<hr/>";
echo "<br/>";
}//elseif is not empty search
elseif($numSearch === 0){
echo "<font color='red'>No Matches.</font>";
}

Answer 1

Do it like this
$i = 1;
while($resGetSearch = mysql_fetch_array($getSearch)){
$highlight = $i == 1 ? 'keywordHighlight' : '';
echo "<tr class='{$highlight}' onclick='getDetails($SearchCdid);' >";
---------------
-------------
-------------
$i++;
}
Only with CSS
or you can highlight it only with css
#highlight tbody tr:nth-child(1){
background: #ff6600;
}
There is more and elegant way to highlight only first row with only css not need to code, consider the example http://jsbin.com/soravuzakahu/1/

Answer 2

You could just add a boolean outside the loop. Like so:
$first = true;
while($resGetSearch = mysql_fetch_array($getSearch)){
if(first == true){
// Add code here that only applies to the first iteration.
}
$first = false;
}

<?php

$i = 0;
while($resGetSearch = mysql_fetch_array($getSearch)){
++$i;
$SearchCdid = $resGetSearch['cdid'];
$SearchFamilyName = $resGetSearch['family_name'];
$SearchGivenName = $resGetSearch['given_name'];
$SearchCompamyCid = $resGetSearch['cid'];

$resSearchCompanyName = mysql_fetch_array($SearchComapnyName);
$companyName = $resSearchCompanyName['company_name'];
if (strlen($companyName) >= 20) {
$companyName = substr($companyName, 0, 10). "" . substr($companyName, -5);
}else{
$companyName = $companyName;
}
// my Highlighted class = keywordHighlight";

Answer 4

Use a flag and set its value to true and while in loop check its value , if its true then print class name and set its value to false. Like $flag=true; then inside while loop check
if($flag==true) {
<td class='yourclassname';
$flag= false;
}

Answer 5

put some flag $f=0;
if f==0 then do something like this:
$highlight="<div class='keywordHighlight'>valur of first row</div>";// instead of dive you can use table also it depends on how you want to display.
$f=$f+1;
and rest in else part.

Answer 6

$first = true;
while ( $resGetSearch = mysql_fetch_array($getSearch) )
{
if ( $first == true )
{
// Add code here that only applies to the first iteration.
$first = false;
}
else
{
// Add code here that only applies to the 2, 3, and so on.
}
}
