Image not properly displayed.
I stored raw data blob (png format). I want to display image, but only symbols are displayed.
Try
echo "<img src=\"data:image/png;base64,".$row['imges']."\" />" ;
Instead of
echo "<img src=data:image/png;<?php echo ".$row['imges']."; ?> />" ;
Is the table name really "newss"?
Don't do things like:
echo "
HTML CODE
";
Do this:
?>
HTML CODE <?php echo $php_code;?>
<?php
You currently trying to use PHP opening Tag <?php within PHP self.
<?php
echo "<?php echo 'test';?>";
?>
PHP won't parse this, but will just echo it as pure text.
Change following line:
<img src=data:image/png;<?php echo ".$row['imges']."; ?> />
to:
<img src="data:image/png;".$row['imges'].";"/>
Also use double quotes for HTML-Parameters like src="path/to/file.format".
Not being lazyis very important in coding!
If everything does not work, what is the output of $row['imges'] ?

I'm trying to show an image (or rather a link to an image) stored in a database and I'd like to get the image to show only if the link is set in the database.
Currently, if the link is not set (value is null), it shows a broken link.
Is there a way to for example use an if-statement and echo a HTML-code?
Something like this:
(The value have been fecthed to array $current in this example:)
<?php
if(isset($current['image']) {
echo "<img src='<?php echo $current['image'];
?>' class='left' style='max-height:20em; max-width:15em; margin-right:1em; margin-top:0;'})">
You used <?php twice, you have problem with quotes, brackets, etc.
<?php
if (!empty($current['image'])) {
echo "<img src='" . $current['image'] . "' class='left' style='max-height:20em; max-width:15em; margin-right:1em; margin-top:0;'>";
} else {
// here you can write for example default no-image image or whatever yo want, if you want
}
Nevermind, got it.
-Solution:
<?php if(isset($current['image'])): ?><img src="<?php echo $current['image']; ?>" class="left" style="max-height:20em; max-width:15em; margin-right:1em; margin-top:0;})">
<?php endif; ?>
<?php
if(isset($current['image'])) {
?>
<img src='<?php echo $current['image'];?>' class='left' style='max-height:20em; max-width:15em;
margin-right:1em; margin-top:0;'>
<?php
}
?>
I have a problem in a file : movies.php
I want to show all movies on the files when there is no id, and if the id exists, i want to show the movie with that id , i used :
echo "<div id='head'>$title</div>";
echo "<div id='bodyar'>$content</div> <br />
<hr>Category : <span class='date'>$moviecategory</span></hr>
<hr>Views : <span class='date'>$views_numimg</span></hr>
<hr></hr> <br />"; exit;}
$orderposts = mysql_query("select * from movie ");
echo "<div class='bodypanelposts'>";
while ($rowar = mysql_fetch_assoc($orderposts)) {
$id_po = $rowar['id'];
$picture = $rowar['picture'];
$title = $rowar['title'];
echo "<div id='movieall'><table id='classing' border='0'
cellspacing='2'><tr> <td>";
echo "<a href='movies.php?id=$id_po'><img src='$picture' alt='$image_caption' width='180' height='250'><br /></div><div class='movies'>$title</div></a><br />LIKE BOX GOES HERE</tr></td></table></div>";
}
The problem is , after using that , the footer is not appearing anymore ..
I want it to appear.
To let PHP know it has to start interpret the code, you need start tags:
<?php
// PHP code here
?>
You should also concat variables by a dot instead of putting into the quotes:
echo "<div id='head'>" . $title . "</div>";
(Some might say this is not important but it is IMO, PHP can't handle it properly in every case.)
When using exit;, you tell PHP to quit and flush the result to the browser.
There is also a closing } bracket after the exit, but I don't see any opening { bracket.
A better way to handle your HTML is to do it like this:
<div id='head'><?=$title?></div>
<div id='bodyar'><?=$content?></div>
<br />
<table>
<tr><td>Category</td><td><span class='date'><?=$moviecategory?></span></td></tr>
<tr><td>Views</td><td><span class='date'><?=$views_numimg?></span></td></tr>
</table>
<div class='bodypanelposts'>
<?php
while ($rowar = mysql_fetch_assoc($orderposts)) {
$id_po = $rowar['id'];
$picture = $rowar['picture'];
$title = $rowar['title'];
echo <<<HTML
<div id='movieall'>
<table id='classing' border='0' cellspacing='2'>
<tr><td><a href='movies.php?id=$id_po'><img src='$picture' alt='$image_caption' width='180' height='250'><div class='movies'>$title</div></a>
<br />LIKE BOX GOES HERE
</td></tr>
</table>
</div>
HTML;
?>
</div>
Notice the <?= tags to do inline PHP echo statements, allowing you to write HTML without having to wrap them in echo statements.
You can also use HEREDOC syntax to echo out a large chunk of HTML with variables inline.
These two methods make it much easier to reason about what your code is outputting.
imagedisplay.php(view)
<html>

<h3>Your file was successfully uploaded!</h3>
<?php print_r($upload_data); ?> </br>
<?php $str=base_url()."images/".$upload_data['file_name'] ?> </br>
<?php $str=str_replace('http://','',$str) ?>
<?php echo $str; ?>
<img src= '$str'/> </br>
For echo $str; I got the string i need to display th image
but when i pass it to img src.... i am not able to display it on the browswer
Is there any syntactical error or am i missing anything ...pls help?
Just a small syntax problem here.
Embed PHP echo command in the HTML code, like so:
<img src="<?php echo $str; ?>"/> </br>
or embed PHP echo short tags:
<img src="<?=$str?>"/> </br>
In other words: insert the PHP output at the positions, where you need it as HTML content.
I'm trying to call an HTML/PHP content that it's inside my database using:
<?php echo $row_content['conteudo']; ?>
When the row is called the HTML appears correctly but the PHP doesn't.
I belieave it's cause of the echo inside the main echo.
<?php echo "
<h3>Hello</h3>
<?php do { ?>
<div class=\"indios\">
<a href=\"indio.php?id=<?php echo $row_indiosct['id']; ?>\">
<img src=\"galeria/indios/<?php echo $row_indiosct['foto']; ?>\" alt=\"<?php echo $row_indiosct['nome']; ?>\" />
<br /><?php echo $row_indiosct['nome']; ?></a></div>
<?php } while ($row_indiosct = mysql_fetch_assoc($indiosct)); ?> "
?>
The line one of this code is the same echo as the first code field, it's not repeating, it's there just for help and to understand where is the problem.
I already fixed some quotation marks but it gives an error in the line of the 1st echo.
That is some of the ugliest code I have ever seen...
<?php
echo '
<h3>Hello</h3>';
while ($row_indiosct = mysql_fetch_assoc($indiosct))
{
echo '
<div class="indios">
<a href="indio.php?id='.$row_indiosct['id'].'">
<img src="galeria/indios/'. $row_indiosct['foto'].'" alt="'.$row_indiosct['nome'].'" />
<br />'.$row_indiosct['nome'].'</a>
</div>';
}
?>
You could also use the HEREDOC syntax.
Don't do this. Multi-line echoes, especially when you've got embedded quotes, quickly become a pain. Use a HEREDOC instead.
<?php
echo <<<EOL
<h3>Hello</h3>
...
<div class"indios">
...
EOL;
and yes, the PHP inside your echo will NOT execute. PHP is not a "recursively executable" language. If you're outputting a string, any php code embedded in that string is not executed - it'll be treated as part of the output, e.g.
echo "<?php echo 'foo' ?>"
is NOT going to output just foo. You'll actually get as output
<?php echo 'foo' ?>
You have misunderstood how PHP works. PHP is processed by the server. When it encounters your script, it sees the following:
<?php echo "some long piece of text that you have told PHP not to look at" ?>
What is the reasoning behind trying to nest PHP calls inside strings?
evaluate code php in string using the function eval(): this post Execute PHP code in a string
<?php
$motto = 'Hello';
$str = '<h1>Welcome</h1><?php echo $motto?><br/>';
eval("?> $str <?php ");
http://codepad.org/ao2PPHN7
also if your need the code buffer output in a string also you can using the ob_start() method:
<?php ob_start(); ?>
<h3>Hello</h3>;
<?php
while ($row_indiosct = mysql_fetch_assoc($indiosct)){ ?>
<div class="indios">
<a href="indio.php?id='<?php echo $row_indiosct['id']'">
<img src="galeria/indios/'<?php echo $row_indiosct['foto'].'" alt="'.$row_indiosct['nome'].'" />
<br />'.$row_indiosct['nome'].'</a>
</div>';
<?php } ?>
I'm echoing quotes through htmlentities($str) and it works the first time, but it's for caption's on images that are being swapped via jQuery when clicked- then the caption shows the html entity ".
How can I echo the text with quotes so that it still appears as a " instead of the $quot; after clicked?
Here's my html
<div class="smallImageWrapper">
<?php if(empty($row_rsPTN['img1'])): echo "" ?>
<?php else: ?>
<span class="smallImage"><img src="../images/products/pbetn/50x50/<?php echo $row_rsPTN['img1']; ?>" alt="<?php echo htmlentities($row_rsPTN['img1caption']); ?>" name="smallImage" id="smallImage1" height="50px" width="50px" /></span>
<?php endif; ?>
and here's my jQuery to swap the images:
$("#smallImage1").bind("click", function() {
$("#largeimage").attr("src","../images/products/pbetn/180x280/<?php echo $row_rsPTN['img1']; ?>");
$("#largeimage").attr("alt","<?php echo htmlentities($row_rsPTN['img1caption']); ?>");
$(".caption").text("<?php echo htmlentities($row_rsPTN['img1caption']); ?>");
});
here's a link to my test site where you can see it occurring:
http://www.imsmfg.com/new/test/products/ptn.php?menuproduct=Lacing%20Strips
Let me know if you need more info.
Thanks!
Change this line:
$("#largeimage").attr("alt","<?php echo htmlentities($row_rsPTN['img1caption']); ?>");
To this:
$("#largeimage").attr("alt","<?php echo addslashes($row_rsPTN['img1caption']); ?>");
jQuery entitizes things automatically, so you don't need to put entities in that quote. You just need to escape any quotes. Hence addslashes.
