PHP code not working properly after first echo function - php

I've been trying to create a web application that functions like a library system, and I am currently working on building the table that will display all books in the system. However, after I close the first echo statement to start building the table in HTML, the app seems to just stop seeing it as code and prints the rest of the PHP code to the screen.
Here is the code in question:
<?php
$db = mysqli_connect('34.224.99.227','root','opendoor','library')
or die ('Could not connect to database');
$result = mysqli_query($db,'SELECT * FROM book');
echo '<table id="table_id" class="display">
<thead>
<tr>
<th>ISBN</th>
<th>Title</th>
<th>Author</th>
<th>Description</th>
<th>Status</th>
</tr>
</thead>
<tbody>';
while($row = mysqli_fetch_array($result)) {
echo '<tr>';
echo '<td>' . $row['isbn'] . '</td>';
echo '<td>' . $row['title'] . '</td>';
echo '<td>' . $row['author'] . '</td>';
echo '<td>' . $row['description'] . '</td>';
echo '<td>' . $row['status'] . '</td>';
echo '</tr>';
}
echo '</tbody></table>';
mysqli_close($db);
?>
And here is the corresponding web page output:
ISBN Title Author Description Status '; while($row = mysqli_fetch_array($result)) { echo ''; echo '' . $row['isbn'] . ''; echo '' . $row['title'] . ''; echo '' . $row['author'] . ''; echo '' . $row['description'] . ''; echo '' . $row['status'] . ''; echo ''; } echo ''; mysqli_close($db); ?>
I'm obviously not too well-versed in PHP, so I'm at a loss as to what the problem could be.

After playing around with the settings of my LAMP stack, I realized that I had apparently configured it with PHP 5 in mind, while I had downloaded PHP 7. Once I fixed the discrepancy, everything worked as intended. Thanks for help nonetheless.

How do I organize data in a PHP search query?

I'm in the process of making a PHP website, where a user can input data, then search through it later, but I can't seem to organize the data :/
Heres my code:
<form action="uploads.php" method="GET"><input id="search" type="text" placeholder="Type here"><input id="submit" type="submit" value="Search"></form></body></html>
When a user searched for their name, it results as so:
firstname=Mickey lastname=Mouse item1= item2= item3= item4= item5= item6=
Is there any way I can add a CSS or something to get the entries to line break or seperate?
In Your display page while displaying the data you can use the <br> tag so that it will display each and every data in different line.
First Name: <?php echo $loopvariable['fname'].'<br />'; ?>
Last Name: <?php echo $loopvariable['lname'].'<br />'; ?>
Like this you can provide for all the data which you print.
Output:
First Name: Name One
Last Name: Name Two
And you can provide as such information using the break tags in separate lines.
Basically in PHP you can echo html code so you can echo <br> statements as in the previous answer you can also echo css and you can create a block of code that you include
<?php
include('SomeMoreCode.php');
?>
You can also echo formatting commands to create a table. Just place the html statements in'' and join html and mysql/php values with .
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>date</th> <th>Home Team</th> <th></th><th></th><th>Away Team</th> <th></th> </tr>";
while($row = mysql_fetch_array( $result )) {
echo "<tr>";
echo '<td>' . $row['date'] . '</td>';
echo '<td>' . $row['hometeam'] . '</td>';
echo '<td>' . $row['fthg'] . '</td>';
echo '<td>' . $row['ftag'] . '</td>';
echo '<td>' . $row['awayteam'] . '</td>';
echo '<td>Edit</td>';
echo "</tr>";
}
echo "</table>";
non mysql - php only
<?php
$date='19/6/16';
$hometeam='Man United';
$fthg='3';
$ftag='2';
$awayteam='Man City';
echo "<table border='1' cellpadding='10'>";
echo "<tr> <th>date</th> <th>Home Team</th> <th></th><th></th><th>Away Team</th> </tr>";
echo "<tr>";
echo '<td>' . $date . '</td>';
echo '<td>' . $hometeam . '</td>';
echo '<td>' . $fthg . '</td>';
echo '<td>' . $ftag . '</td>';
echo '<td>' . $awayteam . '</td>';
echo "</tr>";
echo "</table>";
?>

How can I add a class for td in reference to two columns

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"' : '').
'>';

Display the result by selection each column from a html table using php

Is it possible to have filtering option in each column of html table in which the data is fetched from mysql as we do in excel sheet?
<html>
<?php
// connect to the database
include('connect-db.php');
$result = mysql_query("SELECT * FROM log WHERE type='c' ") ;
echo "<div style='height:auto;'><table border='0' cellpadding='10' class='table table-striped table-bordered'>";
echo "<tr> <th>ID</th> <th>Date</th> <th>Type</th> <th>Batch name</th> <th>No.of Pages</th> <th>User</th><th>file</th><th>Status</th><th></th><th></th></tr>";
// loop through results of database query, displaying them in the table
while($row = mysql_fetch_array( $result )) {
$id=$row['batch_file'];
// echo out the contents of each row into a table
echo "<tr>";
echo '<td>' . $row['id'] . '</td>';
echo '<td>' . $row['assdate'] . '</td>';
echo '<td>' . $row['type'] . '</td>';
echo '<td>'.substr($row['batch_file'], 0, -4).'</td>';
echo '<td>' . $row['no_pages'] . '</td>';
echo '<td>' . $row['assign'] . '</td>';
echo '<td><a href="copy_test_uploads/'.$row['batch_file'].'"target="_blank"><img src="pdf.png" style=width:35px;></td>';
echo '<td>' . $row['status'] . '</td>';
echo '<td>Edit</td>';
echo '<td>Delete</td>';
echo "</tr>";
}
// close table>
echo "</table></div>";
?>
</html>

Execute mysql Querys with jQuery/Ajax and PHP?

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'));
});

PHP- How do you split up an array of different rows thats been put in as one?

I'm trying to make a shopping cart and have managed to submit what checkboxes a user has checked to my shopping cart page. It echos the details from the database but I've realised that I cant get my details to post through on their own.
There is one big group, is there a way to add to my code to ungroup them and put them in a table?
this is the code ive used to post the deatils to my cart:
<?php
if (isset($_POST['games'])) {
$n = count($_POST['games']);
for($i=0; $i < $n; $i++)
echo $_POST['games'][$i];
}
?>
this is the database:
<?php
$con = pg_connect(bla bla);
if (!$con){
die('Could not connect: ' . pg_error());
}
$result = pg_query("SELECT * FROM CSGames");
echo "
<table>
<tr>
<th>Title</th>
<th>Platform</th>
<th>Description</th>
<th>Price</th>
<th>Select</th>
</tr>";
while($row = pg_fetch_array($result)){
echo"<tr>";
echo "<td>" . $row['1'] . "</td>";
echo "<td>" . $row['2'] . "</td>";
echo "<td>" . $row['3'] . "</td>";
echo "<td>" . $row['4'] . "</td>";
echo '<td><input type="checkbox" name="games[]" value="' . $row['0'] . $row['1'] . $row['2'] . $row['3'] . $row['4'] . '"/></td>';
echo"</tr>";
}
echo"</table>";
pg_close($con);
?>
The problem with the data you are getting from $_POST['games'] lies in how you are populating the 'value' property of the input.
While personally I would add a game ID to your database table and only put the value of the game's ID as the input's value and just look up the data for the selected games on your cart output page, I will stick with the framework within how you have done things for my answer.
This is your problem:
<input type="checkbox" name="games[]" value="' . $row['0'] . $row['1'] . $row['2'] . $row['3'] . $row['4'] . '"/>
Here you are just concatenating a bunch of strings together without any sort of separator that you can later split on. I would simply suggest doing something like this:
<input type="checkbox" name="games[]" value="' . $row['0'] . '|||' . $row['1'] . '|||' . $row['2'] . '|||'. $row['3'] . '|||' . $row['4'] . '"/>
I have added triple pipes ||| that you can later use to split these fields on.
So when you get to outputting, you can do something like this:
<?php
if (isset($_POST['games'])) {
?>
<table>
<tr>
<tr>
<th>Title</th>
<th>Platform</th>
<th>Description</th>
<th>Price</th>
</tr>
<?php
foreach($_POST['games'] as $game_string) {
$game = explode('|||', $game_string);
?>
<tr>
<?php
foreach ($game as $attr) {
?>
<td><?php echo $attr; ?></td>
<?php
}
?>
</tr>
<?php
}
?>
</table>
<?php
}
?>
