i have this problem i hope some of you can help me with. I try to make a html link that get the link from my database.
echo "<p><pre><a href=$Feed['socialfacebook']><img src=facebook-24.png></a></pre></p>
You need to put the link in '".$variable ."' and the image src should be in ' ', too.
echo "<p><pre><a href='".$Feed['socialfacebook']."'><img src='facebook-24.png'></a></pre></p>";
Double-quoted strings don't work with array elements quite like that. You should close and concatenate the strings.
echo "<p><pre><img src=facebook-24.png></pre></p>"
You might also want to put some quotes on your attributes.
Close your string with a double quote and end your statement with a semi-colon,
When getting array elements inside a string literal like you're doing, leave out the key quotes,
Use single quotes around your attribute in case of any spaces:
echo "<p><pre><a href='$Feed[socialfacebook]'><img src=facebook-24.png></a>";
Eval.in
u need to put the variable $Feed['socialfacebook'] in " . $Feed['socialfacebook'] ."
echo "<p><pre><a href=" . $Feed['socialfacebook'] . "<img src=facebook-24.png></a></pre></p>";
and don't forget the ;
Shouldn't it be:
echo "<p><pre><a href='$Feed["socialfacebook"]'><img src=facebook-24.png></a>";
Don't forget that is href="".

echo "<td>".$value["rating"]."<div class=ratingOutput data-average=".$rates." **data-id="$value["id"]"**></div>".$newline.$rateHere.$starOutput."</td>";
I want data-id to be and integer value, but cannot set it to any int for example even if i change the above code to this
echo "<td>".$value["rating"]."<div class=ratingOutput data-average=".$rates." **data-id="4"**></div>".$newline.$rateHere.$starOutput."</td>";
I get an error as such:
syntax error, unexpected '$value' (T_VARIABLE), expecting ',' or ';'
You're having an error concatenating of your string.
echo "<td>".$value["rating"]."<div class=ratingOutput data-average=".$rates." **data-id=". 4 . "**></div>".$newline.$rateHere.$starOutput."</td>";
Change this:
echo "<td>".$value["rating"]."<div class=ratingOutput data-average=".$rates." **data-id="4"**></div>".$newline.$rateHere.$starOutput."</td>";
To this:
echo '<td>'.$value['rating'].'<div class="ratingOutput" data-average="' . $rates . '" data-id="' . $value['id'] . '"></div>'.$newline.$rateHere.$starOutput.'</td>';
The best way when working with html in PHP is to use single quotes because normally you will be using double quotes for your attribute, by then you will need to escape the double quote. for the attributes you will be using.
Whenever I build HTML in PHP code, I use the heredoc syntax:
echo <<< EOT
<td>
{$value['rating']}
<div class="ratingOutput" data-average="$rates" data-id="4"></div>
$newline
$rateHere
$starOutput
</td>
EOT;
...something like that.
So you don't have to worry about escaping your double-quotes or concatenation. You can format your HTML so that it's easier to read (perhaps you don't need that $newline variable, if it's just a newline character, I can't tell).
(It doesn't have to be used with echo either, you can use it in variable assignment $html = <<< EOT - no whitespace after your token or it will fail!
If you need the last new-line character in your variable then you need a blank line before your closing token, because the closing character sequence is actually \nEOT;\n.
Many examples in articles use EOT as the token, but I abandoned that for _ a long time ago, shorter.
I have a problem with my page. I am displaying images using PHP Loop statement. Now I want to assign these images with different id's. Example first loop the first image displayed will have an id="img1", next loop and second image has id="img2". Numbers on the id changes based on the loop iteration variable, while "img" is constant. Here's my code:
for ($i=1;$i<=6;$i++){
echo ("<img src='gangjeong.png' width='113' id='img'.$i>");
}
but it's not working. Any help would be much appreciated.
UPDATE: I got it to work now, thanks for the answers. The working code is:
for ($i=1;$i<=6;$i++){
echo ("<img src='gangjeong.png' width='113' id='img$i'>");
}
You can't use unescaped single quotes if you start your string by single quotes.
These are the possibilities you have:
Using double quotes inside single quotes:
for ($i=0;$i<6;$i++){
echo ('<img src="gangjeong.png" width="113" id="img' . ($i+1) . '" />');
}
Using escaped single quotes inside single quotes (ugly):
for ($i=0;$i<6;$i++){
echo ('<img src=\'gangjeong.png\' width=\'113\' id=\'img' . ($i+1) . '\' />');
}
Using double quotes for starting/ending the string:
for ($i=0;$i<6;$i++){
echo ("<img src='gangjeong.png' width='113' id='img" . ($i+1) . "' />");
}
Using escaped double quotes inside double quotes (ugly):
for ($i=0;$i<6;$i++){
echo ("<img src=\"gangjeong.png\" width=\"113\" id=\"img" . ($i+1) . "\" />");
}
Quotes inside quotes are a no no without proper escaping. Also you have a missing > for the img tag. This should do:
for ($i=1;$i<=6;$i++){
echo "<img src='gangjeong.png' width='113' id='img".$i."'>";
}
Where's your escape characters? Your quotes need escaping, or put your HTML part in double quotes and PHP strings in single, or vice versa. Just make sure you're not confusing start and end quotes.
your syntax is not correct, use:
for ($i=1;$i<=6;$i++){
echo '<img src="gangjeong.png" width="113" id="img'.$i.'" alt="">';
}
Use:
for ($i=1;$i<=6;$i++){
echo "<img src=\"gangjeong.png\" width=\"113\" id=\"img$i\">";
}
Hi i have been using this php echo statement
echo "<a href = 'message_delete_script_outbox.php?id=".$row['id']."'"."onclick='return
confirm(/Are you sure, you want to delete?/)'>Delete</a>";
The statement is working i am seeing this message /Are you sure, you want to delete?/ instead of this Are you sure, you want to delete?
Your quote nesting is a little messed up. Try to follow these rules:
Outer quote = " (This marks the beginning and end of the string)
Inner quote = \" (Escaped as to not flag "beginning/end of string")
Third-tier quote = ' (Literal quote)
Fourth-tier quote = \' (Literal quote that will be generated as an escaped outer quote)
Result:
echo "<a href=\"message_delete_script_outbox.php?id=".$row['id']."\"onclick=
\"return confirm('Are you sure, you want to delete?')\">Delete</a>";
More info about quote nesting: http://blog.opensourceopportunities.com/2007/10/nested-nested-quotes.html
You enclose the message in quotes, and those quotes need to be escaped to avoid confusing the PHP script:
echo "<a href = 'message_delete_script_outbox.php?id=".$row['id']."'"."onclick='return
confirm(\"Are you sure, you want to delete?\")'>Delete</a>";
Just add double quotes and escape them
echo "<a href = 'message_delete_script_outbox.php?id=".$row['id']."' onclick='return confirm(\"Are you sure, you want to delete?\")'>Delete</a>";
I am not sure if you added a new line when you posted here, but you should know you cannot have that script on 2 lines.
I cant get this to work and its driving me mad, pls help
echo "<a href='#' onclick='javascript:$.jGrowl
(\"".$_SESSION['product_description'][$i]."\")' >?</a>";
the problem comes down to the 'product_description' - those single ' marks are breaking it, what should i do sigh
EDIT: if i replace the .$_SESSION['product_description'][$i]. with a bunch of charecters it works, its not a problem with anything but PHP and those ''
Chances are the real problem lies with the $.jGrowl. Within double quotes, PHP tries to parse found variables. e.g.
$foo = 'foo';
echo "This is foo: $foo"; // output: This is foo: foo
So, to avoid this you need to escape the $ using \$ within the string...
echo "...\$.jGrowl..."
See this demo.
Keep this here for reference:
Escape them with a backslash, like you would with double quotes. e.g.
// which ever quote is used to encapsulate the string
// must be escaped within the output.
echo 'Hello, \'world!\''; // output: Hello, 'world!'
echo "Hello, \"world!\""; // output: Hello, "world!"
// but, if you use the opposite quote, it does not need
// to be escaped for output.
echo 'Hello, "world!"'; // output: Hello, "world!"
echo "Hello, 'world!'"; // output: Hello, 'world!'
See the PHP Docs on strings for more information and what characters need escaping.
Are you missing your opening "?
echo "<a href='#' onclick='javascript:$.jGrowl(\"".$_SESSION['product_description'][$i]."\")' >?</a>";
Make it
echo "<a href='#' onclick='javascript:$.jGrowl(\"".$_SESSION['product_description'][$i]."\")' >?</a>";
Try:
echo "<a href='#' onclick='javascript:\$.jGrowl(\"".str_replace('"','\"',$_SESSION['product_description'][$i])."\");' >?</a>";
You need to ensure you are escaping any double quotes within the value...
This one works for me:
echo "<a href=\"#\" onclick=\"javascript:$.jGrowl('".$_SESSION['product_description'][$i]."')\" >?</a>";
I am using like
$myPage .= '<td><a href=\'javascript:editProduct('
.$row['id']
.',"'
.$row['name']
.'")\'>Edit</a></td>';
where $row['name'] has quotes in its value. it breaks. how do i solve the issue both from php side and js side...
$row['name'] is value from DB. and it will have value like pradeep's and pradeep"s also
i used like
$myPage .= '<td><a href=\'javascript:editProduct('.addslashes($row['id']).',"'.addslashes($row['name']).'")\'>Edit</a></td>';
it solves the issue of double quotes. but when i have single quotes in value the javascrit link looks like
javascript:editProduct(28,"pradeep\
it actually breaks..
And how do i strip down the slashes added by addslashes in javascript..
UPDATE - FINAL CODE
$myPage .= '<td><a href=\'javascript:editProduct('.$row['id'].',"'.htmlentities($row['name'],ENT_QUOTES).'")\'>Edit</a></td>';
and js looks like
function editProduct(id,name){
alert(name);
}
can any one solve my issues
Try:
$myPage .= "<td><a href='javascript:editProduct({$row['id']},\""
. htmlentities( $row['name'] )
. "\")'>Edit</a></td>";
htmlentities default behaviour is to convert double quotes and leave single quotes alone, if you require converting single and double quotes, then call it like this:
htmlentities( $row[ 'name' ], ENT_QUOTES )
Also, using { .. } in "..." strings is the correct way to substitute variables.
The PHP string
'<a href=\'javascript:editProduct('.$row['id'].',"'.$row['name'].'")\'>';
outputs (assuming some values)
<td><a href='javascript:editProduct(123,"abc")'></td>
Presumably it breaks if $row['name'] contains a " quote. You could replace such quotes with a \" in the string before you output it using str_replace('"', '\"', $row['name'])
