So i've been trying to get one record and edit it by pressing the button that is created in that table, but honestly, i have no idea how to do that. Dx Can anyone help me with this? (Yes, i want the button created for each record. You know, so at the end of every row in the table, every record will have it's own button.)
while($rArt = mysqli_fetch_array($sql)){
echo '<tr><td>' . $rArt['ArtID'] . '</td>';
echo '<td>' . $rArt['FiliaalID'] . '</td>';
echo '<td>' . $rArt['Productnaam'] . '</td>';
echo '<td>' . $rArt['Inkoopprijs'] . '</td>';
echo '<td>' . $rArt['Voorraad'] . '</td>';
echo '<td>' . $rArt['Min_voorraad'] . '</td>';
$voo = $rArt['Voorraad'];
$minvoo = $rArt['Min_voorraad'];
$nodig = $minvoo * 2 - $voo;
$chosen = $rArt['ArtID'];
echo '<td>' . $nodig . '</td>';
echo '<td><input type="submit" name="bestel" value="Bestel"></td></tr>';
if(isset($_GET['bestel'])){
$query = mysqli_query($mysql, "
UPDATE artikel a, voorraad v
SET v.voorraad = v.voorraad + '$nodig'
WHERE a.artid = v.artid
AND v.voorraad = '$chosen'");
}
}
I wouldn't use submit in this case, but just a suggestion:
Why don't you try it this way:
<table>
<tr>
<td>Artikel ID</td>
<td> **<a href="bestelpagina/edit/id/1">** </td>
</tr>
</table>
So you can create an action called Edit in which you can do the changes.
Read the comment in the solution as they are important.
while($rArt = mysqli_fetch_array($sql)){
// echo '<tr><td>' . $rArt['ArtID'] . '</td>';
//The above line i removed and added the line below
echo '<tr><td>' .'<a href=\'admin.php?ArtID='.$rArt['ArtID'].'\'>'.$rArt['ArtID'] .'</td>';
echo '<td>' . $rArt['FiliaalID'] . '</td>';
echo '<td>' . $rArt['Productnaam'] . '</td>';
echo '<td>' . $rArt['Inkoopprijs'] . '</td>';
echo '<td>' . $rArt['Voorraad'] . '</td>';
echo '<td>' . $rArt['Min_voorraad'] . '</td>';
$voo = $rArt['Voorraad'];
$minvoo = $rArt['Min_voorraad'];
$nodig = $minvoo * 2 - $voo;
$chosen = $rArt['ArtID'];
echo '<td>' . $nodig . '</td>';
//echo '<td><input type="submit" name="bestel" value="Bestel"></td></tr>';
//removed this as you dont need input button here.
}///Your while loop should close here not in the ent
if(isset($_GET['bestel'])){
$query = mysqli_query($mysql, "
UPDATE artikel a, voorraad v
SET v.voorraad = v.voorraad + '$nodig'
WHERE a.artid = v.artid
AND v.voorraad = '$chosen'");
}
//} I remove this tag as your while loop should close before isset function

Hi I am having a problem displaying the 24 H volume name in coinmarketcap api it roduces an error when i call it but other values are working perfectly it may bebecause the 24h volume starts with a number. I want to know how will i get it. Thank you. Here is my current code
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<table>
<tbody>
<tr>
<th>Name</th>
<th>Symbol</th>
<th>Rank</th>
</tr>
<?php
ini_set('max_execution_time', 300);
// $tick = file_get_contents('https://api.coinmarketcap.com/v1/ticker/bitcoin/');
$url ='https://api.coinmarketcap.com/v1/ticker/?start=0&limit=1000';// path to your JSON file
$data = file_get_contents($url); // put the contents of the file into a variable
$characters = json_decode($data); // decode the JSON feed
// echo $characters[0]->name;
foreach ($characters as $character) {
echo '<tr>';
echo '<td>' . $character->name . '</td>';
echo '<td>' . $character->symbol . '</td>';
echo '<td>' . $character->rank . '</td>';
echo '<td>' . $character->price_usd . '</td>';

echo '<td>' . $character->last_updated . '</td>';
echo '</tr>';
}
?>
</tbody>sdsdf
</table>

In order to access fields named in that fashoin you need to wrap them with {''}. So you need to write $character->{'24h_volume_usd'}.

Basically my end result is that I am getting one table row, instead the two I am getting. Any suggestions? The table I have populates everything but is only running once, instead of posting for each line I have where stock is equal to zero.
See the snippet below. P.S. Don't mix templates and database layer, it's a bad smell...
<?php
// establish connection to $conn variable
$query = mysqli_query($conn, "SELECT * FROM `midterm` WHERE stock='0'");
echo '<table>';
echo '<tr><th>ID</th><th>Part Number</th><th>Description</th><th>Stock</th><th>Price</th><th>Received</th></tr>';
while ($row = mysqli_fetch_assoc($query)) {
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['part_number'] . '</td>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['stock'] . '</td>';
echo '<td>' . $row['price'] . '</td>';
echo '<td>' . $row['received_date'] . '</td>';
echo '</tr>';
}
echo '</table>';
mysqli_close($conn);
?>
The problem is in closing of </table> It should be kept outside the loop.
while ($row = mysqli_fetch_assoc($query)) {
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['part_number'] . '</td>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['stock'] . '</td>';
echo '<td>' . $row['price'] . '</td>';
echo '<td>' . $row['received_date'] . '</td>';
echo '</tr>';
// echo '</table>';// this is wrong.
};
echo '</table>';// this is correct. closing table inside loop is wrong, do it outside the loop.
You can simply use a while loop to do it like below:
<?php
// establish connection to $conn
$query = mysqli_query($conn, "SELECT * FROM `midterm` WHERE stock='0'");
echo '<table>';
echo '<tr><th>ID</th><th>Part Number</th><th>Description</th><th>Stock</th><th>Price</th><th>Received</th></tr>';
while ($row = mysqli_fetch_assoc($query)) {
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['part_number'] . '</td>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['stock'] . '</td>';
echo '<td>' . $row['price'] . '</td>';
echo '<td>' . $row['received_date'] . '</td>';
echo '</tr>';
}
echo '</table>'; // this should be outside the loop
mysqli_close($conn);
?>
Or if you want to use a foreach then write an extra function for it:
<?php
function mysql_fetch_all($result) {
$rows = array();
while ($row = mysql_fetch_array($result)) {
$rows[] = $row;
}
return $rows;
}
// establish connection to $conn
$query = mysqli_query($conn, "SELECT * FROM `midterm` WHERE stock='0'");
echo '<table>';
echo '<tr><th>ID</th><th>Part Number</th><th>Description</th><th>Stock</th><th>Price</th><th>Received</th></tr>';
foreach (mysql_fetch_all($result) as $row){
echo '<tr>';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['part_number'] . '</td>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['stock'] . '</td>';
echo '<td>' . $row['price'] . '</td>';
echo '<td>' . $row['received_date'] . '</td>';
echo '</tr>';
}
echo '</table>'; // this should be outside the loop
mysqli_close($conn);
?>
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>';
}
?>

I have a PHP Script which lists all Applications from a Databse in a HTML Table. In an own row I want two buttons. Accept and decline
Accept should set the status to "accepted" for the id i klicked on accept.
The Same for decline.
This should update the status in the mysql database.
My Script at the moment:
echo '<table border="1">';
echo '<tr>
<th>ID</th>
<th>Name</th>
<th>Alter</th>
<th>E-Mail</th>
<th>KD</th>
<th>Steam</th>
<th>Spiele</th>
<th>Status</th>
<th>Accept</th>
<th>Decline</th>
</tr>';
while($row = mysql_fetch_object($ergebnis))
{
echo '<tr>';
echo '<td>' . $row->id . '</td>';
echo '<td>' . $row->name . '</td>';
echo '<td>' . $row->age . '</td>';
echo '<td>' . $row->mail . '</td>';
echo '<td>' . $row->kd . '</td>';
echo '<td>' . $row->steam . '</td>';
echo '<td>' . $row->spiele . '</td>';
echo '<td>' . $row->status . '</td>';
echo '</tr>';
}
echo '</table>';
I want my script to be dynamic, so I don't have to refresh the page after every change. Is it possible to do this with jQuery or Ajax? If yes, how do I do it?
change <tr> to <tr class="clickable" data-id="' . $row->id . '">
attach an event handler to tr.clickable
$('tr.clickable').on('click', function(element) {
$.get('changeStatus.php?' + $(element).data('id'));
});
improve the code above
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));
