I am running this code in a PHP file
<?php
if(empty($item)){
echo "Your cart is empty";
}
else{
echo '<table id="cart_table"><tr><th>Item</th><th>Price</th><th></th></tr>' ;
for($i = 0;$i< count($item);$i++){
if(!empty($item[$i])){
$numRow++;
echo '<tr><td>' . "<img src = 'images/$photo[$i].jpg'>" .'</td>';
echo '<td>' .'$' . $item[$i] . '</td>';
echo '<td>' . '<button id= "btn" onclick = "function(){
<script type="text/javascript">
document.getElementById("cart_table").deleteRow('. $numRow .');
}"> Remove</button>'.'</tr>' ;
}
}
echo '</table>';
}
?>
Please consider these lines of code only from the above snippet:
echo '<td>' . '<button id= "btn" onclick = "function(){
<script type="text/javascript">
document.getElementById("cart_table").deleteRow('. $numRow .');
}"> Remove</button>'.'</tr>' ;
}
The result of this code is:
The result I am trying to achieve is:
Is it possible to achieve this result? The result is going to be a button with the label "Remove" and with the onClick property that calls a INLINE(I know it's bad practice, but I have a good reason for it) function which executes some lines of code.
Try not to mix up HTML and PHP together, if there is a need to mix HTML and PHP, try in proper formatting.
<?php
if(empty($item)):
?>
<span>Your cart is empty</span>
<?php
else:
?>
<table id="cart_table">
<tr>
<th>Item</th>
<th>Price</th>
<th></th>
</tr>
<?php
for($i = 0;$i< count($item);$i++):
if(!empty($item[$i])):
$numRow++;
?>
<tr>
<td><img src ='images/<?php echo $photo[$i].jpg; ?>'/></td>
<td>$<?php echo $item[$i]; ?></td>
<td><button id= "btn" onclick = "deleteFromCart('<?php echo $numRow; ?>')"> Remove</button></td>
</tr>
<?php
endif;
endfor;
?>
</table>
<?php
endif;
?>
<script>
function deleteFromCart(rowToDelete){
document.getElementById("cart_table").deleteRow(rowToDelete);
}

I have one function and my echo is:
echo '<tr>
<td align="center" style="padding:5px;"><img src="/chat/emotes/smile.png" onclick="insertSmiley("hallo")"> <br>:illuminati:</td>
</tr>'
The problem is that onclick="insertSmiley("hallo")" must be with ' and not with ". If I put this in html everything works, but in nothing happens in php echo when I click.
My index.php have this script in body:
<script type="text/javascript">
function insertSmiley(smiley)
{
var currentText = document.getElementById("send");
var smileyWithPadding = " " + smiley + " ";
currentText.value += smileyWithPadding;
currentText.focus();
}
</script>
and the other code is in my chat.php:
echo '<textarea id="send" maxlength="125" rows="2" placeholder="Enter your message"></textarea>
<tr>
<td align="center" style="padding:5px;"><img src="/chat/emotes/smile.png" onclick="insertSmiley("hallo")"> <br>:illuminati:</td>
</tr>
I really think that the problem is because I cant use '' in echo and I need it for onClick...('hallo').
use \' to just print '
Backslashes are used in PHP to escape special characters within quotes. As PHP does not distinguish between strings and characters
If your write like this
echo 'check it \' out';
it will give output like this
check it ' out
So use like this
echo '<tr>
<td align="center" style="padding:5px;"><img src="/chat/emotes/smile.png" onclick="insertSmiley(\'hallo\')"> <br>:illuminati:</td>
</tr>'
The fact that you are not echoing any variable within the echo statement, simply add the PHP tags outside of your code:
//Your PHP code here
?>
<tr>
<td align="center" style="padding:5px;">
<img src="/chat/emotes/smile.png" onclick='insertSmiley(" hallo")'>
<br>:illuminati:
</td>
</tr>
<?php
// Continue your php code
In case you have to echo a variable in your HTML, do it this way:
$greetings = "Hallo";
//Your PHP code here
?>
<tr>
<td align="center" style="padding:5px;">
<img src="/chat/emotes/smile.png" onclick="insertSmiley('<?php echo $greetings; ?>')">
<br>:illuminati:
</td>
</tr>
<?php
Try this:
<?php
echo "<textarea id="send" maxlength="125" rows="2" placeholder="Enter your message"></textarea>";
echo "<tr>";
echo "<td align="center" style="padding:5px;"><img src="/chat/emotes/smile.png" onclick="insertSmiley("hallo")"> <br>:illuminati:</td>";
echo "</tr>";
?>
You can use:
onclick="insertSmiley(\'hallo\')"
Like in the title I would like to use a variable inside the hyperlink to use it into the modal window.
I am not using bootstrap, it is a custom code but it works until I try to put some kind of <a href='#openModal?id=".$VARIABLE."'>
Is it possible to do that?
Regards
Update:
<?php
$query = "SELECT * FROM USER";
$result = mysqli_query ($connection,$query)
or die ("You couldn’t execute query");
echo "<div class='admin-table'>
<table cellspacing='15'>
<td><h3>Last Name</h3></td>
<td><h3>Name</h3></td>
<td><h3>Phone</h3></td>
<td><h3>Address</h3></td>
<td><h3>Postcode</h3></td>
<td><h3>Date of Birth</h3></td>
<td><h3>Email</h3></td>
<td><h3>Password</h3></td>
<td><h3>Role</h3></td>
</tr>";
while ($row = mysqli_fetch_array ($result, MYSQLI_ASSOC))
{
extract ($row);
echo "<tr>\n

echo "<tr><td colspan ='15'><hr></td></tr>\n";
}
echo "</table></div>\n";
?>
<div id="openModal?id=<?php echo $USER_ID; ?>" class="modalDialog">
<div>X
<h2>$USER_ID</h2>
</div>
</div>
It is working the modal but its just taking the last id, I have to think another solution to pass the variable.
Many thanks for your help
Update 2:
Thank you very much! Now its working,
<?php
$query = "SELECT * FROM USER;";
$result = mysqli_query ($connection,$query) or die ("You couldn’t execute query");
//First echo the table with all your data as you want
echo "
<div class='admin-table'>
<table cellspacing='15'>
<tr>
<td><h3>Last Name</h3></td>
<td><h3>Name</h3></td>
<td><h3>Phone</h3></td>
<td><h3>Address</h3></td>
<td><h3>Postcode</h3></td>
<td><h3>Date of Birth</h3></td>
<td><h3>Email</h3></td>
<td><h3>Password</h3></td>
<td><h3>Role</h3></td>
</tr>";
//Fetch all rows for each user
while ($row = mysqli_fetch_array ($result, MYSQLI_ASSOC)) {
extract ($row);
echo "
<tr>
<td>$USER_LASTNAME</td>
<td>$USER_FIRTSNAME</td>
<td>$USER_PHONE</td>
<td>$USER_ADDRESS</td>
<td>$USER_POSTCODE</td>
<td>$USER_DOB</td>
<td>$USER_EMAIL</td>
<td>$USER_PASSWORD</td>
<td>$USER_ROLE</td>
<td><a href='admin_user.php?id=".$USER_ID."'>Delete</a></td>
<td><a href='#openModal?id=".$USER_ID."'>Edit</a></td>
<div id='openModal?id=".$USER_ID."' class='modalDialog'>
<div><a href='#close' title='Close' class='close'>X</a>
<h2>".$USER_ID."</h2>
<p>You can have additional details here.</p>
</div>
</div>
</tr>
<tr>
<td colspan ='15'><hr></td>
</tr>";
}
echo"
</table>
</div>";
?>
Try this:
echo '<a href="#openModal?id='.$VARIABLE.'">';
Update:
echo '<td>Edit</td>\n';
echo '<td>Delete</td>\n';
any reason you can't use onclick ?
<a href="#" onclick="myJsFunc();">
<script>
function myJsFunc() {
//code to open modal
}
</script>
UPDATE
If i have understood you correct you are trying to make a table showing all users and then when the admin clicks at element a modal pop ups providing additional info for the particular user.
<?php
$query = "SELECT * FROM USER;";
$result = mysqli_query ($connection,$query) or die ("You couldn’t execute query");
//First echo the table with all your data as you want
echo "
<div class='admin-table'>
<table cellspacing='15'>
<tr>
<td><h3>Last Name</h3></td>
<td><h3>Name</h3></td>
<td><h3>Phone</h3></td>
<td><h3>Address</h3></td>
<td><h3>Postcode</h3></td>
<td><h3>Date of Birth</h3></td>
<td><h3>Email</h3></td>
<td><h3>Password</h3></td>
<td><h3>Role</h3></td>
</tr>";
//Fetch all rows for each user
while ($row = mysqli_fetch_array ($result, MYSQLI_ASSOC)) {
extract ($row);
echo "
<tr>
<td>$USER_LASTNAME</td>
<td>$USER_FIRTSNAME</td>
<td>$USER_PHONE</td>
<td>$USER_ADDRESS</td>
<td>$USER_POSTCODE</td>
<td>$USER_DOB</td>
<td>$USER_EMAIL</td>
<td>$USER_PASSWORD</td>
<td>$USER_ROLE</td>
<td><a href='admin_user.php?id=".$USER_ID."'>Delete</a></td>
<td><a href='#openModal".$USER_ID."'>Edit</a></td>
</tr>
<tr>
<td colspan ='15'><hr></td>
</tr>";
}
echo"
</table>
</div>";
//Fetch again the rows to make the modals with the edit info
while ($row = mysqli_fetch_array ($result, MYSQLI_ASSOC)) {
extract ($row);
echo '
<div id="openModal'.$USER_ID.'" class="modalDialog">
<div>X
<h2>'.$USER_ID.'</h2>
<p>You can have additional details here.</p>
</div>
</div>';
}
?>
Old answer before the comments
It seems that single quotes and/or double quotes aren't escaped properly.
Also remember that in PHP string concatenation is made using " . " (dot) and in JavaScript using " + " (plus).
Update 1
I think that if you use the following you will be ok.
echo '<td>Delete</td>';
echo '<td>Edit</td>';
Update 2
Don't forget to add $variable at div too so <a> and div id are the same the same. E.g.
echo '<div id="openModal'.$variable.'" class="modalDialog"></div>';
I want to allow clicking on a whole host table in foreach loop in codeigniter. For some reason, the code does not work for me. Do you have an idea how to fix it?
Thanks in advance
<table class="table table-hover">
<thead>
<tr>
<th>השולח</th>
<th>נשלחה בתאריך</th>
<th>נושא ההודעה</th>
<th>תוכן ההודעה</th>
</tr>
</thead>
<tbody>
<?php foreach ($messages->result() as $row)
{
?>
<script type="text/javascript">
function newDoc() {
window.location.assign("<?php echo base_url();?>/read_messages/<?php echo $row->id;?>")
}
</script>
<?php
echo "<tr>";
echo "<td>".$row->author. "</td>";
echo "<td>".$row->posted_in. "</td>";
echo "<td>".$row->title. "</td>";
echo "<td>".$row->body. "</td>";
?>
onclick="newDoc()";
<?php
echo "</tr>";
}
?>
</tbody>
</table>
</div>
As I understand your question you want fetch click on every row. then your code should be as:
Your Script should be out side
<script type="text/javascript">
function newDoc(id) {
window.location.assign("<?php echo base_url();?>/read_messages/"+id);
}
</script>
<?php foreach ($messages->result() as $row)
{
echo "<tr onclick='newDoc(".$row->id.")'>";
echo "<td>".$row->author. "</td>";
echo "<td>".$row->posted_in. "</td>";
echo "<td>".$row->title. "</td>";
echo "<td>".$row->body. "</td>";
echo "</tr>";
}
?>
You have to assign onClick="newDoc" to html element like
<table onClick="newDoc()">
You have to issues, one your newDoc() function is not assigned to element and two you want create the newDoc function once and only once passing in the $row->id so that its affect changes for each <tr>
<script type="text/javascript">
function newDoc(rowId) {
window.location.assign("<?php echo base_url();?>/read_messages/" + rowId);
}
</script>
<?php
foreach ($messages->result() as $row) {
echo "<tr onlick='newDoc(<?php echo $row->id ?>)'>";
echo "<td>".$row->author. "</td>";
echo "<td>".$row->posted_in. "</td>";
echo "<td>".$row->title. "</td>";
echo "<td>".$row->body. "</td>";
echo "</tr>";
}
?>
I have my database table named material
material:
mat_id mat_name status
1 bolts
2 steel approved
How can I make my button or maybe href link disable when status = 'approved'
on my html table?
like:
option mat_id material name
show button 1 bolts
no button 2 steel
my code for html/php:
<?php
$resource=mysql_query("Select * from material",$con);
while($result2=mysql_fetch_array($resource))
{
?>
<tr>
<th>option</th>
<th>mat_id</th>
<th>material name</th>
</tr>
<tr>
<td align="center">
<?php
$id = $rows['reqraw_id'];
if($rows['status']=="")
{
echo '<a href="addstockout.php?id=$id" > Update </a>';
} ?>
</td>
<td><?php echo $result2['mat_id']; ?></td>
<td><?php echo $result2['mat_name']; ?></td>
</tr>
<?php };?>
There is a problem on this line
echo '<a href="addstockout.php?id=$id" > Update </a>';
It doesn't get the id array from the db.
...
<?php if($result2['status'] == 'approved') { ?>
<td><button disabled="true">Button</button></td>
<?php
} else{ ?>
<td><button>Button</button></td>
<?php } ?>
...
if($result2['status']=="" OR $result2['status']===NULL)
{
echo '<button type="button">Click Me!</button>';
}else{
echo '<button type="button" disabled>Click Me!</button>';
}
<td><?php echo ($result2['status']===NULL)?"button here":"disabled"; ?></td>
I think this should do it:
Instead of
<td>button</td>
put:
<?php
echo '<td><button ';
if(!($result2['status']==="approved"))
{
echo 'disabled="true"';
}
echo '>Click</button></td>';
?>

I'm having this kind of error:

You need to check if argument "id" is passed to the php script first

Not so much an answer to your question, but probably a good suggestion to make your code a lot cleaner- try using PHP Alternative Syntax and moving in and out of PHP to make your HTML clean.
<?php while($row=mysqli_fetch_array($result)):?>
<tr class="record">';
<td><?php echo $row['articletitle'];?>
<td>Edit
<input type='hidden' name='id' value='<?php echo $row['articleid'];?>'></td>
<td>
<div align="center">
Delete
</div>
</td>
</tr>
<?php endwhile;?>
<form method="post" id="myForm" action="postview.php">
<input type="hidden" name="myID">
</form>
$sql="SELECT * FROM blog WHERE articleid='".$id."'";
try this line
That isnt an error, but a notice, which is lowlevel It simple means $_GET['id'] doesnt hav a value
echo $example['something']; // will give undefined index notice
$example['something'] = 'abc';
echo $example['something']; // No notices
Your website should be domain.ext/?id=123, if not, this notice will show.
