i have the following script to retrieve sql data:
// Present data if avail
if ($result->num_rows > 0) {
// Query output in tabels
while($row = $result->fetch_assoc()) {
echo '<tr> <td class="tg">' .$row["id"]. '</td>' . "\n";
echo '<td class="tg">' .$row["fname"]. '</td>' . "\n";
echo '<td class="tg">' .$row["lname"]. '</td>' . "\n";
echo '<td class="tg">' .$row["make"]. '</td></tr>' . "\n";
}
// if no records
} else {
echo "0 results";
}
How can i replace duplicates in the row 'fname' for empty strings? (records are being ordered by fname)
The script you showed us doesn't retrieve SQL data - it just displays it. If you managed to write the code above then this should be obvious:
$prevname='';
while($row = $result->fetch_assoc()) {
echo '<tr> <td class="tg">' .$row["id"]. '</td>' . "\n";
echo '<td class="tg">'
. ( $row["fname"] == $prevname ? '' : $row["fname"])
. '</td>' . "\n";
echo '<td class="tg">' .$row["lname"]. '</td>' . "\n";
echo '<td class="tg">' .$row["make"]. '</td></tr>' . "\n";
$prevname=$r["fname"];
}

I have a render of row of database
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> <th></th> <th></th></tr>";
// loop through results of database query, displaying them in the table
while($row = mysql_fetch_array( $result )) {
// echo out the contents of each row into a table
echo "<tr>";
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['tex1'] . '</td>';
echo '<td>' . $row['tex2'] . '</td>';
echo '<td>' . $row['tex3'] . '</td>';
echo '<td>' . $row['tex4'] . '</td>';
echo '<td>' . $row['tex5'] . '</td>';
echo '<td>' . $row['tex6'] . '</td>';
echo '<td>' . $row['tex7'] . '</td>';
echo '<td>' . $row['tex8'] . '</td>';
echo '<td>' . $row['tex9'] . '</td>';
echo '<td>' . $row['tex10'] . '</td>';
echo '<td>Edit</td>';
echo '<td>Delete</td>';
echo "</tr>";
}
// close table>
echo "</table>";
And in the tex1 is a date, my problem is for a class for tr, when the tex2 is empty and the date of tex1 is older than 30 days, tr have class red, the date of tex1 is inserted manually,how can I do to change the class on the basis of this?
I'm not sure if I understood what you wanted properly but I'll give it a shot. You want to add a class ("red") to the , whenever the condition is met that either the date is older than 30 days old (tex1) or the First Name is empty (tex2).
echo "<table border='1' cellpadding='10'>";
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>ID</th> <th>First Name</th> <th>Last Name</th> <th></th> <th></th></tr>";
// loop through results of database query, displaying them in the table
while($row = mysql_fetch_array( $result )) {
// echo out the contents of each row into a table
// I assume since you're just printing it out, the date is a String
// So first convert it to a timestamp
$date = strtotime($row['tex1']);
// Determine the difference, I'm doing it this way to make it easy for you to understand
$days = 60*60*24*30; // 30 days
if (empty($row['tex2']) || time()-$date > $days) {
echo '<tr>';
} else {
echo '<tr class="red">';
}
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['tex1'] . '</td>';
echo '<td>' . $row['tex2'] . '</td>';
echo '<td>' . $row['tex3'] . '</td>';
echo '<td>' . $row['tex4'] . '</td>';
echo '<td>' . $row['tex5'] . '</td>';
echo '<td>' . $row['tex6'] . '</td>';
echo '<td>' . $row['tex7'] . '</td>';
echo '<td>' . $row['tex8'] . '</td>';
echo '<td>' . $row['tex9'] . '</td>';
echo '<td>' . $row['tex10'] . '</td>';
echo '<td>Edit</td>';
echo '<td>Delete</td>';
echo "</tr>";
}
// close table>
echo "</table>";
You should check for the conditions what you have mentioned in your question. And this can be done like this.
if(strtotime($row['tex1']) + 30 * 24 * 60 * 60 < time() && $row['tex2'] =="") {
$class="class='red'";
} else {
$class= "";
}
echo "<tr $class>";// id condition satisfies, class='red' will get echo, else echo will be null.
Try a conditional when writing the element:
echo '<tr'.
( ((strtotime($row['tex1']) < strtotime('30 days ago'))
&& (empty($row['tex2']))) ? ' class="red"' : '').
'>';
I have table called reservations. It displays reservations made by users. I want highlight records in current date using end date.
Php code
$result2 = mysql_query("SELECT * FROM reservations WHERE hotel_id = '1' ORDER BY end");
while ($row = mysql_fetch_array($result2)) {
echo '<tr>';
echo '<td class="contacts">' . $row['fname'] . ' ' . $row['lname'] . '</td>';
echo '<td class="contacts">' . $row['start'] . '</td>';
echo '<td class="contacts">' . $row['end'] . '</td>';
echo '<td class="contacts">' . $row['qty'] . '</td>';
echo '</td>';
echo '<td class="contacts">' . $row['room_type'] . '</td>';
echo '<td class="contacts">' . '<a href=out.php?id=' . $row["res_id"] . '>' . 'Check Out' . '</a>' . '</td>';
echo '</tr>';
}
I'd do that at frontend side, but if you want to compute than in PHP, you will need to compare the date from $row and current date and add a class or a style tag to the .
Like so:
$rowHasCurrentDate = $row['date'] == date('Y-m-d');
echo '<tr' + ($rowHasCurrentDate ? ' class="highlight-row"' : "") + '>';
instead of
echo '<tr>';
You can replace the 'class="highlight-row"' with 'style="background-color:red"' if you want to do it without touching frontend side at all.
The example is kinda spaghetti-code, but you can move this logic somewhere else after you get it working.
I am assuming that your start date is current date. This is css thing, i have given you solution to you.
<html>
<head>
<style>
.currdate
{
background-color:red; //change this color to whatever you wish to change to
}
</style>
</head>
<body>
<?php
$result2 = mysql_query("SELECT * FROM reservations WHERE hotel_id = '1' ORDER BY end");
while ($row = mysql_fetch_array($result2)) {
echo '<tr>';
echo '<td class="contacts">' . $row['fname'] . ' ' . $row['lname'] . '</td>';
echo '<td class="contacts currdate">' . $row['start'] . '</td>';
echo '<td class="contacts">' . $row['end'] . '</td>';
echo '<td class="contacts">' . $row['qty'] . '</td>';
echo '</td>';
echo '<td class="contacts">' . $row['room_type'] . '</td>';
echo '<td class="contacts">' . '<a href=out.php?id=' . $row["res_id"] . '>' . 'Check Out' . '</a>' . '</td>';
echo '</tr>';
}
?>
<body>
</html>
How can I add different maximum width to my table columns? I'd also like to have an auto line break when I write something into the columns. Here's my code:
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>ID</th> <th>Kategorie</th> <th>Titel</th> <th>Betroffene Seiten</th> <th>Beschreibung</th><th>prioritaet</th><th>Status</th><th>Eingereicht von</th><th>Umsetzung mit Release</th><th>Dev. Kommentar</th><th>Entwickler</th><th></th> <th></th></tr>";
// loop through results of database query, displaying them in the table
while($row = mysql_fetch_array( $result )) {
// echo out the contents of each row into a table
echo "<tr>" ;
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['kategorie'] . '</td>';
echo '<td>' . $row['titel'] . '</td>';
echo '<td>' . $row['betroffen'] . '</td>';
echo '<td>' . $row['beschreibung'] . '</td>';
echo '<td>' . $row['prioritaet'] . '</td>';
echo '<td>' . $row['status'] . '</td>';
echo '<td>' . $row['eingereicht'] . '</td>';
echo '<td>' . $row['umsetzung'] . '</td>';
echo '<td>' . $row['kommentar'] . '</td>';
echo '<td>' . $row['entwickler'] . '</td>';
echo '<td>bearbeiten</td>';
echo '<td>löschen</td>';
echo "</tr>";
}
// close table>
echo "</table>";
you can set a width to your td in pixels or %. setting in one td will set it for the column.
echo '<td style="width:40px">' . $row['id'] . '</td>';
I didn't understood you intenstion by:
"when I write something into the columns."
you can use the \n to get new lines in your php code. just add it to your code where appropriate.
you can see here
you can also use <br /> in your HTML to get the same line break.
You can do as following to break line in column and keep max width,
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>ID</th> <th>Kategorie</th> <th>Titel</th> <th>Betroffene Seiten</th> <th>Beschreibung</th><th>prioritaet</th><th>Status</th><th>Eingereicht von</th><th>Umsetzung mit Release</th><th>Dev. Kommentar</th><th>Entwickler</th><th></th> <th></th></tr>";
// loop through results of database query, displaying them in the table
while($row = mysql_fetch_array( $result )) {
// echo out the contents of each row into a table
echo "<tr>" ;
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['id'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['kategorie'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['titel'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['betroffen'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['beschreibung'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['prioritaet'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['status'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['eingereicht'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['umsetzung'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['kommentar'], 20, "<br />\n") . '</td>';
echo '<td width="'.strlen($row['id'])+5.'">' . wordwrap($row['entwickler'], 20, "<br />\n") . '</td>';
echo '<td>bearbeiten</td>';
echo '<td>löschen</td>';
echo "</tr>";
}
// close table>
echo "</table>";
using strlen function set max width to td and using wordwrap break column value to new line
I have query which retrieves and then prints rows of data, but what I am trying to is just add a number in the '$rank' column. So for example if there are 10 rows that come up in the query, I want the query to put a 1 in the first row, 2 in the second and so on...
It is not so much a ranking system, I just want a number to appear in the left column that counts each row. The query I posted below just puts a '1' in the column, can anyone help?
<?php
$bg = '#ffffff'; // Set the background color.
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
$i=0;
$rank = $i+1;
$bg = ($bg=='#e1e3e6' ? '#cdcdcf' : '#e1e3e6'); // Switch the background color.
echo '<tr bgcolor="' . $bg . '">';
echo '<td align="center">' . $rank . '</td>';
echo '<td align="center">' . $row['sales_model'] . '</td>';
echo '<td align="center">' . $row['sales_customer_firstname'] . ' ' . $row['sales_customer_surname'] . '</td>';
echo '<td align="center">' . $row['sales_vin'] . '</td>';
echo '<td align="center">' . $row['sales_rda'] . '</td>';
echo '<td align="center">' . $row['sales_commission_no'] . '</td>';
echo '<td align="center">' . $row['sales_points'] . '</td>';
}
?>
Here is an example
$i = 0;
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
/* while code here */
++$i; //increment the counter by 1
}
In PHP MYSQL_FETCH_ASSOC is omitting Last Row. This never happened. But this time it put me into soup at the last moment.
Even I've put up mysql_num_rows the result is 14 records -- but on list it shows only 13 records and the 14th record is omitted.
Any kind of help is Appreciated.
$uno = $_GET["uno"];
$xtc1 = 'select * from rform where uno="' . $uno . '" order by rno DESC';
$xtc = mysql_query($xtc1) or die('User Reservation Retrival Error : ' . mysql_error());
$trno = mysql_fetch_assoc($xtc);
$trow = mysql_num_rows($xtc);
echo '<p>List of Onlilne Reservations made by <strong style="font-weight:bold; color:red;">' . ucwords($trno["cname"]) . ' (' . $trow . ')</strong></p>';
echo '<table cellpadding="5" cellspacing="0" border="1">';
echo '<tr>';
echo '<td colspan="5" style=" font-size:14px; text-align:center; font-weight:bold; color:red;">' . ucwords($trno["cname"]) . '</td>';
echo '</tr>';
echo '<tr>';
echo '<th>R.NO</th>';
echo '<th>From</th>';
echo '<th>To</th>';
echo '<th>Date & Time of<Br>Travel</th>';
echo '<th>Reserved On</th>';
echo '</tr>';
while($mtn = mysql_fetch_assoc($xtc)){
$dt = $mtn["csdate"] . ' ' . $mtn["ctime"];
echo '<tr>';
echo '<td>' . $mtn["rno"] . '</td>';
echo '<td>' . $dt . '</td>';
echo '<td>' . $mtn["caddr"] . '</td>';
echo '<td>' . $mtn["cdest"] . '</td>';
echo '<td>' . date('d-M-Y',strtotime($mtn["tstamp"])) . '</td>';
echo '</tr>';
}
echo '</table>';
You have an extra $trno = mysql_fetch_assoc($xtc) that you sem to be discarding. This is your missing row. Just remove that line.
deleting the first $trno = mysql_fetch_assoc($xtc); will solve this problem.
In case you need to read the first line of $xtc before the loop. You can change while loop to do-while, without deleted the first $mtn = mysql_fetch_assoc($xtc);
do{
//whatever
}while($mtn = mysql_fetch_assoc($xtc));
