I'm currently working on a voting project, i have a form that is populated from the database and i managed to use loops to generate radio buttons. However the radio button can only select one answer out of the possible eight, i need it to select an answer in each and every question. i know the radio button names are the same and the need to be different, however its a loop so i dont know how to change the names. any help?
Here is the code
<?php $title="POLLS | Voting - Home";
require_once( "includes/session.php");
include( "includes/connection.php");
include( "includes/header.php");
$query="SELECT user_id FROM users WHERE user_id={$_SESSION['user_id']}" ;
$result=mysql_query($query,$connection);
$row=mysql_fetch_row($result);
$_SESSION[ 'user_id']=$row[0]; ?>

When I click page number in DataTable, it is not moving to next page instead it loads the whole page again.
But if I click the DataTable sorting button and again I click the pagination page number, the DataTable is working fine. Can anyone help me to solve this. Thanks in advance.

The above code is giving this error but in my console I didn't get any error information.
Below is my code for downloading some files from a webpage.
Everything works fine except target="_blank". This button does nothing even though the link is correct. If I right click and press open in a new tab it works but when i press the button it does nothing.
<?php
while ($row = $result->fetch_assoc()) {
$i+=1;
$name = $row["filename"];
$location = "../uploadedfiles/" . $name;
?>
<div class="row">
<p><hr>Name : <?php echo $row["name"] ?> <br> Contact Details : <?php echo $row["number"] ?><br></p>
</div>
<div class="row">
<p>Date Sent: <?php echo date("F d Y-- H:i:s.", filectime($location)) ?><br></p>
</div>
<div class="row">
<p><p> <?php echo $i ?> ) <?php echo substr($name, 10) ?> <a href="../uploadedfiles/<?php echo $name; ?>" target='_blank'><button type='button' class='btn btn-info'>View / Download </button></a></p></p>
</div>
<?php }
?>
<hr>
<?php
} else {
echo "0 results";
}
$con->close();
The way you have created button within the anchor tag is not one of the best practices to be followed.
Ideally you should do something like this:
View/Download
Hope this helps.
I'm currently working on a super simple Online shop idea with a shopping cart. At the end i want to print out a table with the products you ordered. Currently using a foreach but i have no idea how to solve this. I tried to use sessions as a way to give the loop an idea how many different products are ordered. But it seems like the $_SESSION way will take all the current active sessions. And using a simple variable f.e. $piano will make it print 2 rows ( using 2 piano's in my shop, tried to solve it with a if (session active) $piano1 = active. But it seems the foreach statement doesn't give a whoop about that and will print 2 rows anyways.
Sorry for the long block of text. Here's my page. Again apologies. I just started php.
Variable names are dutch but that shouldn't really matter for you guys i think.
Starting from line 103.
Thanks in advance!

Create an array variable in the $_SESSION array and do a foreach loop on that
$_SESSION['cart']['piano1'] = 'piano1';
$_SESSION['cart']['piano2'] = 'piano2';
$cart = $_SESSION['cart'];
foreach ($cart as $key => $item) {
//do something with $item or $key

I'm creating a blog site and I got stuck in this phase where I want to allow authors to delete their own posts, they can already see the delete button below each of their posts. In the DB table I have an author, content and ID of the article. Now I need to get the specific ID of the article that they want to delete, but I have no idea how to do this, the delete button is the same for every article, so I can't use that for help. I have this code to get articles from my DB and the button click code ready. For better imagination here is an image of the site -
... previous code
<?php }
$articles->ArticlesConn();
$result = mysql_query("SELECT * FROM articles_table");
while($row = mysql_fetch_array($result)){ // loop to generate content
?>
<div class="container"> // responsive stuff
<div class="row"> // responsive stuff
<div class="twelve columns"> // responsive stuff
<?php
echo "<h3>" . $row['Title'] . "</h3>
<p>" . $row['Content'] . "</p>"; ?>
</div>
</div>
<div class="row">
<div class="eight columns">
<address><?php echo "Author - " . $row['Author']; ?> </address><br><br><br> /// nick of the author below each article
</div>
<div class="four columns">
<?php
if ($row['Author'] == $_SESSION["username"]) // show delete button if the logged user is an author of generated article
{ ?>
<input type="button" name="delete" value="Delete article"/>
<?php } ?>
</div>
</div>
</div>
<?php
}
?>
To solve your problem, you should add a form to wrap your input.
This form will call the page itself. In this form there is a hidden input with the value of the article id. So when you submit the form, you can get the article id via $_POST['name of the hidden input'].
I will show you the code :
<?php }
if (isset($_POST['article-id'])) {
// prevent SQL injection
$articleId = mysql_real_escape_string($_POST['article-id']);
$res = mysql_query('DELETE FROM articles_tab WHERE id='.$articleId);
if (!$res) {
die(mysql_error());
}
}
$articles->ArticlesConn();
$result = mysql_query("SELECT * FROM articles_table");
while($row = mysql_fetch_array($result)){ // loop to generate content
?>
<div class="container"> // responsive stuff
<div class="row"> // responsive stuff
<div class="twelve columns"> // responsive stuff
<?php
echo "<h3>" . $row['Title'] . "</h3>
<p>" . $row['Content'] . "</p>"; ?>
</div>
</div>
<div class="row">
<div class="eight columns">
<address><?php echo "Author - " . $row['Author']; ?> </address><br><br><br> /// nick of the author below each article
</div>
<div class="four columns">
<?php
if ($row['Author'] == $_SESSION["username"]) // show delete button if the logged user is an author of generated article
{ ?>
<form method="post">
<input type="hidden" name="article-id" value="<?php echo $row['ID'] ?>"/>
<input type="submit" value="Delete article"/>
</form>
<?php } ?>
</div>
</div>
</div>
<?php
}
But you should use mysqli or PDO instead of the old mysql extension, look at this : http://php.net/manual/en/function.mysql-query.php
If I add this Bootstrap Tab into html code, it works perfectly:
<ul class="nav nav-tabs">
<li class="active">Hello</li>
<li>Empty</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="hello">
<h3>Hello my Friend!</h3>
<p>hello</p>
</div><!-- #end #hello -->
<div class="tab-pane" id="empty">
<h3>Just gonna be empty...</h3>
<p>Yup. Nothin' here.</p>
</div><!-- #end #empty -->
</div>
But in those tap I need to connect to my database so show some information, my code is:
<ul class="nav nav-tabs">
<li class="active">Facilities</li>
<li>Course Fee</li>
</ul>
<div class="tab-content">
<div class="tab-pane active" id="facilities">
<h3>Just gonna be empty...</h3>
<p>Yup. Nothin' here.</p>
<?php echo "<table>";
$userpic = '<img src="images/user.png"/>';
while ($roww = mysqli_fetch_array($usercomment)){
$cm_fac = $roww['facilities'];
$name = $roww['UserName'];
$time = $roww['CmtDate'];
echo '<tr>';
echo '<td>';
//i put some info here as table
echo '</td>';
echo '</tr>';
}
echo "</table>";
?>
</div><!-- end of facilities-->
<div class="tab-pane" id="fee">
<h3>Hello my Friend!</h3>
<p>hello</p>
<?php echo "<table>";
$userpic = '<img src="images/user.png"/>';
while ($roww = mysqli_fetch_array($usercomment)){
$cm_fee = $roww['fee'];
$name = $roww['UserName'];
$time = $roww['CmtDate'];
echo '<tr>';
echo '<td>';
//some info here too
echo '</td>';
echo '</tr>';
}
echo "</table>";
?>
</div><!-- end of fee-->
</div> <!--end of tab-content-->
but it doesn't work. Can anyone show me my problem?
Thank you for your time.
You maybe can try this:
<div class="tab-pane" id="fee">
<h3>Hello my Friend!</h3>
<p>hello</p>
<!-- open the 'while' -->
<?php
while ($roww = mysqli_fetch_array($usercomment)){
$cm_fac = $roww['facilities'];
$name = $roww['UserName'];
$time = $roww['CmtDate'];
?>
<!-- your table -->
<table>
<tr>
<td>
<?php echo "your data here"; ?>
</td>
</tr>
</table>
<?php } ?> <!-- close the 'while' here -->
</div>
Check results of your query.
You can use $roww = mysqli_fetch_array($usercomment, MYSQLI_ASSOC); to fetch data.
