    <p>Let's say I have a dynamically-created table that is filled with data from a MySQL db from a <code>SELECT</code> sentence.</p> <p>Now, I need to access a variable that is defined inside of an <code>if</code> clause inside of the table, from the outside. For making that, I'm using some <code>$_SESSION</code> values, but when I try to apply this coloring to the entire row, it colors up all the table instead of a single row in which the session value is stored. I'm guessing that I need to save also the <code>$RowCt</code> value, but dunno how.</p> <p>I've been with this problem for quite a while, and looks like I'm a little bit blinded after looking at this code continuously. Any help is appreciated.</p> <p>Code:</p> <pre><code>&lt;?php include("../includes/header.php")?&gt; &lt;div class="content" align="center"&gt; &lt;?php function SQLResultTable($Query) { $link = mysql_connect("localhost", "...", "...") or die('Could not connect: ' . mysql_error()); mysql_select_db("...") or die('Could not select database'); $Table = ""; $Table.= "&lt;table border='0' align='center'&gt;"; $Result = mysql_query($Query); //Execute the query if(mysql_error()) { $Table.= "&lt;tr&gt;&lt;td&gt;MySQL ERROR: " . mysql_error() . "&lt;/td&gt;&lt;/tr&gt;"; } else { //Header Row with Field Names $NumFields = mysql_num_fields($Result); $Table.= "&lt;tr style=\"background-color: #D00000; float:center; font-size:14px; color: #FFFFFF;\" align='center'&gt;"; for ($i=0; $i &lt; $NumFields; $i++) { if ((mysql_field_name($Result, $i))=="a1") { $Table.= "&lt;th&gt;a1&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a2") { $Table.= "&lt;th&gt;a2&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a3") { $Table.= "&lt;th&gt;a3&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a4") { $Table.= "&lt;th&gt;a4&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a5") { $Table.= "&lt;th&gt;a5&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a6") { $Table.= "&lt;th&gt;a6&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a7") { $Table.= "&lt;th&gt;a7&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a8") { $Table.= "&lt;th&gt;a8&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a9") { $Table.= "&lt;th&gt;a9&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a10") { $Table.= "&lt;th&gt;a10&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a11") { $Table.= "&lt;th&gt;a11&lt;/th&gt;"; } else if ((mysql_field_name($Result, $i))=="a12") { $Table.= "&lt;th&gt;a12&lt;/th&gt;"; } else { $Table.= "&lt;th&gt;" . mysql_field_name($Result, $i) . "&lt;/th&gt;"; } } $Table.= "&lt;/tr&gt;"; $RowCt = 0; while($Row = mysql_fetch_assoc($Result)) { $timezone = new DateTimeZone( "Europe/London" ); $date = new DateTime(); $date-&gt;setTimezone( $timezone ); $now = $date-&gt;format( 'H:i' ); if (!isset($_SESSION['b2'])) { $Table.="&lt;tr style='background-color:red;'&gt;"; } else if (!isset($_SESSION['b1'])) { $Table.="&lt;tr style='background-color:yellow;'&gt;"; } else { $Table.="&lt;tr style='background-color:white;'&gt;"; } foreach($Row as $field =&gt; $value) { if ($field == 'b1') { if ($value &gt; $now) { $_SESSION['b1'] = $b1; $Table.= "&lt;td style='font-size:14px;' align='center'&gt;$value&lt;/td&gt;"; } else { $Table.= "&lt;td style='font-size:14px;' align='center'&gt;$value&lt;/td&gt;"; } } else if ($field == 'b2') { if ($value &gt; $now) { $_SESSION['b2'] = $b2; $Table.= "&lt;td style='font-size:14px;' align='center'&gt;$value&lt;/td&gt;"; } else { $Table.= "&lt;td style='font-size:14px;' align='center'&gt;$value&lt;/td&gt;"; } } else { $Table.= "&lt;td style='font-size:14px;' align='center'&gt;$value&lt;/td&gt;"; } } $Table.= "&lt;/tr&gt;"; } $Table.= "&lt;tr style=\"background-color: #FFFFFF; font-size:10px; color: #000000;\"&gt;&lt;td colspan='$NumFields'&gt;&lt;br /&gt;Query returned " . mysql_num_rows($Result) . " result(s).&lt;/td&gt;&lt;/tr&gt;"; } $Table.= "&lt;/table&gt;"; return $Table; } ?&gt; &lt;?php echo "&lt;div align='center'&gt;&lt;u&gt;&lt;strong&gt;&lt;a href='index.php'&gt;Query Results&lt;/a&gt;&lt;/strong&gt;&lt;/u&gt;&lt;/div&gt;"; echo SQLResultTable("SELECT a1,a2,a3,a4,a5,a6,a7,a8,a9,a10,a11,a12 FROM test_db ORDER BY a6"); ?&gt; &lt;/div&gt; </code></pre> <p></p> <p>Now, the <code>$now</code> value returns the actual hour, i.e. 08:30; and <code>$value</code> on fields <code>b1</code> and <code>b2</code> returns a similar value on the same format that is stored from a previous form.</p> <p>The deal is this: When it's late (value on field b1 is greater than now), it colors up the row on yellow. If it's very late (value on field b2 is greater than now), it colors up the row on red. Otherwise, the row is on a white background-color.</p> <p>With the code above, it colors up the entire table. And can't find how to undo this so it colors <em>just</em> the row on which the session value is stored, aka where its late or very late.</p> <p>Any help is appreciated, ask if you need any more data.</p>

    1. CONot answering your initial question, but please try to cleanup the code first. It is readable, but there alot of redundancies. P.e. the `foreach`-loop has multiple conditions which all result to the same comclusion (`Table.= "<td style...`). Just put commands into a condition which are really dependand on the condition. If it doesn't depend on it, don't put it there. Just moving your multiple `$Table`-commands onto the beginning of the `foreach`-loop saves you alot of lines of code. And back to your question...it seems to be more of a CSS problem, not php related. Pls focus on this instead.

    2. COThanks for this answer. I'll try to simplify it, even thought it's not my original code. More onto the original problem, I don't think that it's *just* a css problem, that's why I've posted it this way. :)

Querying!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
