I'm building a php/sql crud.
sql query select: user = user id is not working...
What sql statement do i use to show only the users account info?
$stmt = $pdo->prepare($sql);
$stmt->execute();
$users = $stmt->fetchAll(PDO::FETCH_ASSOC);
foreach ($users as $user) {
echo '<tr>';
echo '<td>';
echo $user['id'];
echo '</td>';
echo '<td>';
echo $user['username'];
echo '</td>';
echo '<td>';
echo '<a href="detail.php?id=';
echo $user['id'];
echo '">';
echo 'detail';
echo '</a> ';
echo '<a href="bewerk.php?id=';
echo $user['id'];
echo '">';
echo 'bewerk';
echo '</a> ';
echo '<a href="delete.php?id=';
echo $user['id'];
echo '">';
echo 'delete';
echo '</a>';
echo '</td>';
echo '</tr>';
}
?>

I'm trying to list multiple record from MySQL Database using PHP but when grouping it returns only one record from database, below is my PHP code I'm using.
<?php
include "connection.php";
$query = "select * from lectureupload GROUP BY submittedOn";
$result=mysqli_query($conn, $query);
while ($row = mysqli_fetch_array($result)) {
echo '<table class="table">';
echo '<thead>';
echo '<td><strong>ID</strong></td>';
echo '<td><strong>Title</strong></td>';
echo '<td><strong>Semester</strong></td>';
echo '<td><strong>Teacher</strong></td>';
echo '<td><strong>Lecture Link</strong></td>';
echo '<td><strong>Submitted On</strong></td>';
echo '</thead>';
echo '<div class="section-header">';
echo '<br>';
echo '<h3>'.$row['submittedOn'].'</h3>';
echo '</div>';
echo '<tr >';
echo '<td>'.$row['id'].'</td>';
echo '<td>'.$row['title'].'</td>';
echo '<td>'.$row['semester'].'</td>';
echo '<td>'.$row['teacherName'].'</td>';
echo '<td>'.$row['lectureLink'].'</td>';
echo '<td>'.$row['submittedOn'].'</td>';
echo '</tr>';
echo '</table>';
}
mysqli_close($conn);
?>
The current Result it gives me is somewhat like that,
My Database table is this.
Solution to this problem will be highly appreciated.
Regards.
You can't use GROUP BY clause to retrieve all records from that table. GROUP BY will always return one row per GROUP BY CONDITIONAL_COLUMN. I will suggest you below modification:
<?php
include "connection.php";
//ORDER BY submittedOn will make sure the records retrieved in ordered as per submittedOn.
$query = "select * from lectureupload ORDER BY submittedOn";
$result = mysqli_query($conn, $query);
$submitted_on_keys = array();
while ($row = mysqli_fetch_array($result)) {
if (!in_array($row['submittedOn'], $submitted_on_keys)) {
if (count($submitted_on_keys) > 0) {
//It means we have already created <table> which needs to be closed.
echo '</table>';
}
$submitted_on_keys[] = $row['submittedOn'];
echo '<table class="table">';
echo '<thead>';
echo '<td><strong>ID</strong></td>';
echo '<td><strong>Title</strong></td>';
echo '<td><strong>Semester</strong></td>';
echo '<td><strong>Teacher</strong></td>';
echo '<td><strong>Lecture Link</strong></td>';
echo '<td><strong>Submitted On</strong></td>';
echo '</thead>';
echo '<div class="section-header">';
echo '<br>';
echo '<h3>' . $row['submittedOn'] . '</h3>';
echo '</div>';
}
echo '<tr >';
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['title'] . '</td>';
echo '<td>' . $row['semester'] . '</td>';
echo '<td>' . $row['teacherName'] . '</td>';
echo '<td>' . $row['lectureLink'] . '</td>';
echo '<td>' . $row['submittedOn'] . '</td>';
echo '</tr>';
}
if (count($submitted_on_keys) > 0) {
//There is last <table> which needs to be closed.
echo '</table>';
}
mysqli_close($conn);
?>
You should group it in your PHP code rather than your SQL.
Something like this:
$lectures = [];
$result = mysqli_query($conn, "select * from lectureupload");
while ($row = mysqli_fetch_array($result)) {
$lectures[$row['submittedOn']][] = $row;
}
foreach ($lectures as $submittedOn => $rows) {
echo '<table class="table">';
echo '<thead>';
echo '<td><strong>ID</strong></td>';
echo '<td><strong>Title</strong></td>';
echo '<td><strong>Semester</strong></td>';
echo '<td><strong>Teacher</strong></td>';
echo '<td><strong>Lecture Link</strong></td>';
echo '<td><strong>Submitted On</strong></td>';
echo '</thead>';
echo '<div class="section-header">';
echo '<br>';
echo '<h3>'.$submittedOn.'</h3>';
echo '</div>';
foreach ($rows as $row) {
echo '<tr >';
echo '<td>'.$row['id'].'</td>';
echo '<td>'.$row['title'].'</td>';
echo '<td>'.$row['semester'].'</td>';
echo '<td>'.$row['teacherName'].'</td>';
echo '<td>'.$row['lectureLink'].'</td>';
echo '<td>'.$row['submittedOn'].'</td>';
echo '</tr>';
}
echo '</table>';
}
Anyone can help me out in tabulating this data on PHP/HTML as I am only able to get to raw data which is not formulated. This is the code I am using:
// Price and Flight Select Statements
$pricesql = "select PriceID,RouteID,ClassID,Price from price;";
$printpricesql=mysqli_query($connect,$pricesql);
while($row=mysqli_fetch_array($printpricesql))
{
echo $row['PriceID'];
echo $row['RouteID'];
echo $row['ClassID'];
echo $row['Price'];
}
$flightsql = "select flightid,routeid,departuredate,arrivaldate from
flightschedule;";
$printflightsql=mysqli_query($connect,$flightsql);
while($row=mysqli_fetch_array($printflightsql))
{
echo $row['flightid'];
echo $row['routeid'];
echo $row['departuredate'];
echo $row['arrivaldate'];
}
// Price and Flight Select Statements
$pricesql = "select PriceID,RouteID,ClassID,Price from price";
$printpricesql=mysqli_query($connect,$pricesql);
echo '<table>';
// headers
echo '<tr>';
echo '<th>Price Id</th>';
echo '<th>Route Id</th>';
echo '<th>Class Id</th>';
echo '<th>Price</th>';
echo '</tr>';
while($row=mysqli_fetch_array($printpricesql)) {
echo '<tr>';
echo '<td>'.$row['PriceID'].'</td>';
echo '<td>'.$row['RouteID'].'</td>';
echo '<td>'.$row['ClassID'].'</td>';
echo '<td>'.$row['Price'].'</td>';
echo '</tr>';
}
echo '</table>';
$flightsql = "select flightid,routeid,departuredate,arrivaldate from flightschedule";
$printflightsql=mysqli_query($connect,$flightsql);
echo '<table>';
// headers
echo '<tr>';
echo '<th>Flight Id</th>';
echo '<th>Route Id</th>';
echo '<th>Departure Date</th>';
echo '<th>Arrival Date</th>';
echo '</tr>';
while($row=mysqli_fetch_array($printflightsql)) {
echo '<tr>';
echo '<td>'.$row['flightid'].'</td>';
echo '<td>'.$row['routeid'].'</td>';
echo '<td>'.$row['departuredate'].'</td>';
echo '<td>'.$row['arrivaldate'].'</td>';
echo '</tr>';
}
echo '</table>';
I'm creating a contact based system, i have a contact list and want it to go to a full contact page when i click on a button, but the variable is being detected as a function?
<div id="po2" style="Margin:10% ">
<h1>Contacts</h1>
<?php
$sql = "SELECT * FROM `contacts`";
$query = mysqli_query($conn, $sql);
echo '<table class="data-table">';
echo'<thead>';
echo'<tr>';
echo '<th>Forename</th>';
echo '<th>Surname</th>';
echo '<th>Other</th>';
echo'</tr>';
echo '</thead>';
echo '<tbody>';
while ($row = mysqli_fetch_array($query))
{
echo '<tr>';
echo '<td>'.$row['Forename'].'</td>';
echo '<td>'.$row['Surname'].'</td>';
echo $var==$row['Forename']("<td><a href='View.php?ID= " . urlencode($var) ."'>
<button type='button'>link</button>
</a></td>");
echo '</tr>';
}
echo'</tbody>';
echo '</table>';
?>
</div>
You are using a comparison of $var and the $row. Try setting $var to the $row each loop iteration.
echo '<thead>';
echo '<tr>';
echo '<th>Forename</th>';
echo '<th>Surname</th>';
echo '<th>Other</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
while ($row = mysqli_fetch_array($query))
{
$var = $row['Forename'];
echo '<tr>';
echo '<td>' . $var . '</td>';
echo '<td>' . $row['Surname'] . '</td>';
echo "<td><a href='View.php?ID=" . urlencode($var) . "'><button type='button'>link</button></a></td>";
echo '</tr>';
}
echo '</tbody>';
This code was working perfectly and is retrieving data from my Mysql database. I had a little issue with the path pointing to this script. I am having issues with the hyperlink with the href code line. I have a field in my database that is labled fulltext . I am trying to create a script that allows me display the content of fulltext (echo "{$row['fulltext']}.";) when I click on the Read More button. The hyperlink should be populated with the echo "{$row['title']}.";
What mistake am I making by inserting a href="fulltext.php?=$row['fulltext']
fulltext.php contains htmlspecialchars($_GET["fulltext"]);

}
$sql = 'SELECT title, introtext, created, created_by, catid FROM mydb_items';
mysql_select_db('muslimtimes360');
$retval = mysql_query( $sql, $conn );
if(! $retval )

First of all, you aren't putting the variable into the string properly. Variables are only expanded inside double quotes, not single quotes. And the quotes inside the array index are terminating the string after echo.
Second, you need to give a parameter name before = in the URL.
Third, you were missing the closing double quote for the href attribute.
echo '<td>'; echo ''; echo '<input type="button" value="Read More" />'; echo ''; echo '</td>';
Change the line:
echo '<a href="fulltext.php?=$row['fulltext']>'
to
echo '<a href="fulltext.php?'.$row['fulltext'].'">'
how do i delete a single record in database? i tried with Ajax and it didn't work.here is my code,each row has a unique number ID,so i need that to delet it,but i don't know how to get it.
echo '<tr>';

echo '<a href="korisnik.php?id='.$session_poster_id.'">';
echo '<div class="profile_pic_div" style="margin-top:10px;">';

echo $user['vrijeme'];
echo '</div>';
echo '<a href="delete.php?post_id='.$post_id.'">';
echo '<div class="icon-x" style="margin-left:550px;margin-top:-15px;">';
echo '</div>';
echo '</a>';
echo '<div class="post_div" style="margin-top:30px;">';
if (strlen($user['post']) > 500) {
$user['post'] = substr($user['post'], 0, 500);
$user['post'] = substr($user['post'], 0, strrpos($user['post'], ' ')).'... Read More';}
