failed to open stream: No such file or directory

[momasri]

Hello, this is my first post I hope you guys can help me out here, basically whats going on is I declare a variable "$diree" then I insert it in a function  but its not getting recognized, here is the code:

 

$institutea "some directory";

$dire = str_replace(" ","-",$institutea);

 

 

# SETTINGS

$max_width = 110;

$max_height = 130;

 

$per_page = 5;

$page = $_GET['page'];

 

$has_previous = false;

$has_next = false;

 

function getPictures() {

global $page, $per_page, $has_previous, $has_next;

if ( $handle = opendir($diree.'/') ) { // done changes here

$lightbox = rand();

?><table border="1"><tr><td>

<form action="pro.php" method="post">

 

 

 

<?php

echo "<ul id='pictures'>";

 

$count = 1;

$skip = $page * $per_page;

 

if ( $skip != 0 )

$has_previous = true;

 

while ( $count < $skip && ($file = readdir($handle)) !== false ) {

if ( !is_dir($file) && ($type = getPictureType($file)) != '' )

$count++;

}

$count = 1;

while ( $count < $per_page && ($file = readdir($handle)) !== false ) {

if ( !is_dir($file) && ($type = getPictureType($file)) != '' ) {

 

if ( ! is_dir($dire .'/') ) {  // done changes here

mkdir($dire .'/'); // done changes here

}

if ( ! file_exists($dire .'/'.$file) ) {

makeThumb( $file, $type );

}

 

 

echo '<li>';

echo '<img src="'.$dire .'/'.$file.'" alt="" / width="110" height="110"><br/><input type="checkbox" name="food[]" value='.$file.'>'; // done changes here

echo '</li>';

 

$count++;

 

}

}

echo '</ul>';

?>

</td></tr><tr><td><div align="center"><input type="submit" value="Add"></div></td></tr>

</tr></table></form>

<?php

while ( ($file = readdir($handle)) !== false ) {

if ( !is_dir($file) && ($type = getPictureType($file)) != '' ) {

$has_next = true;

break;

}

}

}

}

 

function getPictureType($file) {

$split = explode($dire .'/', $file);

$ext = $split[count($split) - 1];

if ( preg_match('/jpg|jpeg/i', $ext) ) {

return 'jpg';

} else if ( preg_match('/png/i', $ext) ) {

return 'png';

} else if ( preg_match('/gif/i', $ext) ) {

return 'gif';

} else {

return '';

}

}

 

function makeThumb( $file, $type ) {

global $max_width, $max_height;

if ( $type == 'jpg' ) {

$src = imagecreatefromjpeg($file);

} else if ( $type == 'png' ) {

$src = imagecreatefrompng($file);

} else if ( $type == 'gif' ) {

$src = imagecreatefromgif($file);

}

if ( ($oldW = imagesx($src)) < ($oldH = imagesy($src)) ) {

$newW = $oldW * ($max_width / $oldH);

$newH = $max_height;

} else {

$newW = $max_width;

$newH = $oldH * ($max_height / $oldW);

}

$new = imagecreatetruecolor($newW, $newH);

imagecopyresampled($new, $src, 0, 0, 0, 0, $newW, $newH, $oldW, $oldH);

if ( $type == 'jpg' ) {

imagejpeg($new, $dire .'/'.$file);

} else if ( $type == 'png' ) {

imagepng($new, $dire .'/'.$file);

} else if ( $type == 'gif' ) {

imagegif($new, $dire .'/'.$file);

}

imagedestroy($new);

imagedestroy($src);

}

Hey momasri,

 

if this is your actual code change your first line from

$institutea "some directory";

to

$institutea = "some directory";

[momasri]

Actuly this is my first line few lines of code:

 

require_once("configure.php");

mysql_connect($DBhost,$DBuser,$DBpass) or die("Unable to connect to database" . mysql_error());

@mysql_select_db("$DBName") or die("Unable to select database $DBName" . mysql_error() );

$user_sql = "select institute from $DBtable order by email" ;

 

$user_result = mysql_query($user_sql) or die(mysql_error());

 

while($user_array = mysql_fetch_array($user_result))

{

 

$institutea = $user_array[institute] ;

}

 

$dire = str_replace(" ","-",$institutea);

echo "<br />" . dire;  // this shows a value

// and if I do an echo it works but if I do an echo inside the function is does not work, if I do an echo after the function it works

[BlueSkyIS]

if you want to show it inside the function, you'll need to access as global inside the function

 

function foo() {

    global $dire;

}

sweet thanks, this solves the main problem. now I have a sub question from the above code:

 

in the Body of the page I write:

// this line displays the Pictures I have the "$dire" folder as specified in the code above

<?php getPictures(); ?>

 

 

// this line makes a Previous Page if exists

// and  makes a Next button for Next Page views if they exist

<?php
if ( $has_previous ) 
	echo '<div align="left" style="padding-left:100"><a href="?page='.($page - 1).'">← Previous Page</a></div>';

if ( $has_next )  
	echo '<div align="right" style="padding-right:100"><a href="?page='.($page + 1).'"> Next Page →</a></p>';
?>

 

// the code below gives me numbers for each page, so if the totall number of pictures per page is 5, and i have 20 pictures it gives me links  0 1 2 3 4

 

My question is How can I set my first page to be number "1"  insted of number "0" 

now I am sure the Fix for it is not in the code below, but I thought I would paste all so you can make use of this Picture Pigntaion

$directory = $dire .'/';
if (glob("$directory*.jpg") != false)
{
$filecount = count(glob("$directory*.jpg"));
echo "You have " . $filecount . " Number of Files";
echo "<br/><br/>";	
$total = $filecount / $per_page;
echo "That means you have " .$total . " Number of Pages to view";

for ($i = 0; $i <= $total; $i++)
if ($i >= 0)
{
echo '<p class="prev"> <a href="?page='.$i.'"> '.$i.' </a></p>';
}
}		
?>
