}));
});

</script>

</head>

<body>

<div id="table">
<div id="result" style="background-color:red; height:20px; width:200px;"></div>
<form method="post" action="" id="form" enctype="multipart/form-data">
<table style="width: 100%">
<tr>
<td style="height: 25px; width: 88px">Amount</td>
<td style="height: 25px">

<input name="name" style="width: 161px; height: 29px" type="text" id="name" placeholder="Input amount" onchange/><br/>

</table>
</form>
</div>

</body>

</html>

What i intend to achieve is: Once the value in amount field changes, it goes to a .php page, calculate and display the result as a value in another input field called calculate. When the submit button is pressed, it moves the form to show.php, store in database, and output the result...

I have tried different methods, but am finding it difficult displaying the values in an input field. Please i need your help..

Thanks

Try uploading the file without changing the name.

Try these debugging tips:

Did you check inside the images folder?
Is the image there?
If the image is there what name does it have?
Manually put an image inside the image folder (copy and paste), then try using your code to display the image...

Does it display the manually uploaded image?

Hope this was helpful?

Updated: check the image

Thank you very much, it is now working...... i remove the dirname, and moved the file to the directory straight, without changing the name of the file... SEE MY CHANGES BELOW

I replaced this
$newname=dirname().'/images1/'.$filename;
if(!file_exists($newname))
{
if((move_uploaded_file($_FILES['photo']['tmp_name'],$newname)))
{

with this below
$newname='images1/'.$filename;
if(!file_exists($newname))
{
if((move_uploaded_file($_FILES['photo']['tmp_name'],$newname)))
{

And it is now working..... Thanks, i really appreciate

Try This:

<?php
mysql_connect( "localhost","Gospel","gospel" ) or die( "Could not connect" );
mysql_select_db("picture" or die("could not select db";

$select=mysql_query( "SELECT * from `pix` WHERE sn= 23" ) or die( "could not find" );

if($select)
{
$me=mysql_fetch_array($select);

echo "<img src='$me[image]' height='200' width='120'>";

}
?>

If it doesn't work, you can debug by doing var_dump($me), if the image path is being displayed then the problem is your image tag.

++++++++++++++++++++++++++++++++++++++++++++++

FURTHER OBSERVATIONS

Try this:

$ext = $_FILES["photo"]["type"].

That way you can say :

if(($ext == "image/jpg"....)){
...
}

This checks if your file is an image and that it has the right extension.

Try not to use $_POST directly, or any other global variable directly, its better you use some kind of filter like

filter_input(INPUT_POST, $fieldname) - read more on that here: http://php.net/manual/en/function.filter-input.php

In my opinion, your database connection should be the first thing you do, if the database is not connected, there's no use doing anything else.

I hope this was helpful.

The issue remained the same.... i used the var_dump($me) as u said, and the image path was displayed.... the question now is, how do i rectify it coz i have tried all possible ways i know to no avail.... please help out.. i am getting error such as this

array (size=4)
'sn' => string '11' (length=2)
'fname' => string 'll' (length=2)
'lname' => string 'll' (length=2)
'image' => string 'C:wampwwwimage.sample/images1/20141216_183233.jpg' (length=49)

$ext= substr($filename, strrpos($filename,'.')+1);
if(($ext == "jpg" || $ext == "gif" || $ext == "JPG" || $ext == "jpeg" || $ext == "JPEG" || $ext == "PNG" || $ext == "png" || $ext == "GIF" wink

&&($_FILES['photo']['size']<100000000))
{

$newname=dirname(__FILE__).'/images1/'.$filename;
if(!file_exists($newname))
{
if((move_uploaded_file($_FILES['photo']['tmp_name'],$newname)))
{

mysql_connect("Localhost","Gospel","gospel" wink

echo "<img src='$newname' alt='' height='300' width='500'>"."<br>";
echo "its done! the file has been saved as:".$newname;
}
else
{
echo "Error! problem occured";
}}
else
{
echo "error file:".$_FILES['photo']['name']."already exist";
}}

echo "File format not supported";
}}

}

}

$me=mysql_fetch_array($select);
?>
<img src="<?php echo $me['image']; ?>" alt="" height="200" width="120">
<?php
}
?>
