PHP - Is_file File_exists Filesize Problems On Cifs Mount

I am trying to do a loop which uses file_exists to check if an image exists and if so display it using the following code:

<?php
$i = 1;
while ($i <= 8) {

$filename = $img_loc . "/hovers-800px/" . $image . "-" . $i . ".jpg";

if (file_exists($filename)) {
?>
<a class="fuglybox" rel="gxr" href="<?php echo $filename; ?>"> <!--Main thumbnail image-->
      <img src="<?php echo $img_loc; ?>/product-detail-90px/<?php $image . "-" . $i . ".jpg"; ?>" alt="" width="90" height="90" /></a>
<?php

}

$i++;

}

?>

I have echoed out $filename to check my directory structure and filename is fine and copied the echoed directory out. The structure is however http://Http://www.xxxxxx.com/img/filename.jpg. Could this be whats causing the problem?

I've read as many previous posts as I can find and tried all the suggested solutions but the following simple test code will not work for me (the session variable has been echoed and is correct).   Instead of echoing the correct answer, the if(file_exists($target_file)) skips the true result and always displays the false one.  I've tested it with files that do and don't exist of course.  Here is the code :-

$filename = $_SESSION["filename"];
$target_file = $_SERVER['CONTEXT_DOCUMENT_ROOT'] . '/folder/' . $_SESSION["filename"];

if (file_exists($target_file)) {
    echo 'Selected file is ' . $filename . ' and will be written.';
} else {
    echo "Selected file " . $filename . " doesn't exist.";
} 

I'd really appreciate any help on this please.

<code>
$jpg_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.jpg';
$jpeg_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.jpeg';
$gif_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.gif';
$png_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.png';
$jpg_test = file_exists($jpg_path);
$jpeg_test = file_exists($jpeg_path);
$gif_test = file_exists($gif_path);
$png_test = file_exists($png_path);
</code>

the path is EXACTLY correct I've checked and rechecked and everything. echoed the path and everything else that is relevant. but later when I call if ($png_test == '1') {
blah blah blah
}
it won't return 1. even though I KNOW that the picture is there and it is at that path. if i echo the path in a src for an image it appears. hmm?

Hello all,

I am a real newby to this but need some help with a file_exists / while loop issue i have.

I am trying to show a table of pictures (with their own ID's) but also if someone hasn't uploaded a picture to the server a default picture will be shown instead.

I get the error: Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /home/thefrien/public_html/members1.php on line 103

Here is my code:

$i = 1;
echo "<table border='1' align='center'><tr>";
$result = mysql_query( "SELECT * FROM membership order by L_ID asc" );
while ( $row = mysql_fetch_assoc( $result ) ) {
    echo "<td align='center' bgcolor='#DDDEFF'><a href='profile_view.php?L_ID=".$row["L_ID"] ."'>"
   $pic = 'images/avatar/'. $row["L_ID"] .'s.jpg';   
if (file_exists($pic)) {
   echo '<img src=http://www.thefriendzconnection.co.uk/images/avatar/'.$row["L_ID"] ."s.jpg>";
} else {
   echo '<img src=http://www.thefriendzconnection.co.uk/images/0s.jpg border='0'>';
}
   "</a>
   <br><font size='1' face='Arial, Helvetica, sans-serif'>".$row["name"] ."</font>
   <br><font size='1' face='Arial, Helvetica, sans-serif'>ID: ".$row["L_ID"] ."</font>
   <br>&nbsp;</td>";
    if ( $i % 6 == 0 ) { echo "</tr><tr>"; }
    $i++;
}
mysql_free_result( $result );
echo "</tr></table>";



The line I am having issues with seems to be: $pic = 'images/avatar/'. $row["L_ID"] .'s.jpg';

Any suggestions would be greatfully received

Thanks.

Hi,


I am trying to verify if the given url exists or not, by using file_exists() function.

It always returns 'FALSE' , according to my understanding it happening because the file to be checked on the given url is located in safe mode.

Could anyone please suggest as to how this could be overcome, by similar function or by using alternative method.

Regards
Abhishek Madhani

I'm just trying to find out if php has the ability to check if any file exists, with only part of the filename given..

I have this path:

if (file_exists($dir.'/'.$c_file.'/templ_*')) {

I added a little star.. That star represents whatever the rest of that file is named for this example.. It could be anything.. So can php match any files that start with "templ_", and say that it does or does not exist??

Thanks

I want to get suggested keywords from yahoo api service. When xml file is empty (no keyword), it gives error. To resolve this problem I used this code:
if (file_exists('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2')) {
$xmlmetades = simplexml_load_file('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2');
}


Since it is not a normal .xml file, it is always considered no file, and return nothing.

I'm working on a WordPress theme and I'm trying to build in a simple if statement which will check if the user has add his own logo into the images folder if he doesn't then the name of the blog will appear as normal text in place of the graphic logo.

This is how it looks like:


<?php

$logo_dir = get_template_directory_uri() . "/images/logo.png";

if (file_exists($logo_dir)) { ?>

<li><img src="<?php bloginfo ('template_directory'); ?>/images/logo.png" alt="<?php bloginfo('description'); ?>" /></li>

<?php } else { ?>

<li id='blog_name'><a href="<?php bloginfo('url'); ?>"><?php bloginfo('name'); ?><font>*</font></a></li>

<?php } ?>




I've echo'd out $logo_dir, the URL is correct, but still for some reason it's seeing it as if there would no file exist. If I turn it around into !file_exists then the graphic logo WILL show up. So it's always seeing it as non-existent.

Any ideas why this could be or am I using this function in a wrong fashion? As far as I've understood the PHP manual, this is the correct way of using it.

My setup: (everything on a local network)
Web server: Ubuntu Server 8.10 -- Workgroup
File server: Windows Server 2008 x64 -- domain
Test server: Win 2000 running WAMP -- domain

I'm trying to run the code snippet below. $file is a file on the File server above. It definitely exists.
Running the code below on the Test server works perfectly. But the file cannot be found when running from the Web server.
$file = '//server/share/file.txt';
if (file_exists($file))
echo 'yay!';
else
echo 'error';

What with the safe mode considerations, I've also tried to add:
ini_set('safe_mode', 'Off'); to no effect. And since file, and fopen similarly not work, I'm pretty sure it's not that either.

The File & Test servers are on the same Windows domain, but that's definitely not the reason. I tried the code on a file on a Linux computer in the Workgroup (where the Web server is) with the same results: Test server works, Web server does not.

Please advise; I'm really lost.

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 9

PHP Warning:  file_exists() expects parameter 1 to be string, array given in /home/mysite/public_html/display.mysite.com/wp-content/themes/mytheme/form.php on line 13

I have a form that is having some issues and in the error log I see a bunch of these warnings. What is wrong with this??   I numbered the offending lines below (lines 9 & 13)   Thanks for any help on this.

function CheckExistance($VUrl)

{

/*9*/    if ( file_exists($VUrl) )

        echo $VUrl;

/*13*/    elseif ( file_exists(str_replace('www.display.mysite.com','www.display.com', $VUrl)) )

        echo str_replace('www.display.mysite.com','www.mysite.com', $VUrl);

    else

        echo str_replace('www.mysite.com','www.display.mysite.com', $VUrl);

}

*delurk! It had to happen sooner or later!*

OK, I am totally and utterly stumped. I have this script:

$this->clear_cache ($this->cache_dir, $this->cache_time);

if ($this->cache_time > 0) {
$current_page = $_SERVER ['REQUEST_URI'];
$current_page_encoded = base64_encode($current_page);
$current_page_path = $this->cache_dir . $current_page_encoded;

 if (file_exists($current_page_path)) { // see if there is still a file with the name of the current request URI after cache cleared
                $content = file_get_contents ($current_page_path);

return $content;
                } 
         }

Basically, it is for checking if there is a cached version of the page before running the rest of the script, using the REQUEST_URI as the identifier. So it calls a function to clear the cache, which works fine (and I've tried just deleting the cache files manually anyway).

Then it checks if we are even caching, i.e. if cache time is greater than 0. Then it uses the BASE64-encoded REQUEST_URI (under which name the file would have been cached previously) to check if a file with that name still exists in the cache dir, and if so loads it. Now, this works perfectly with a url like:

mysite/myscript/mysubpage

But when the page has parameters, like:

mysite/myscript/mysubpage?search=widgets

the file_exists function returns TRUE, even though the directory is empty. I did do a clearstatcache(); but it made no difference and anyway, it wouldn't explain why the URI with query string would fail while the regular one would not. And even if something is wrong with my code elsewhere, the fact is it is returning TRUE for a non-existent file.

Can someone prevent my slide into insanity?!

I'm getting back into web coding after 5 years and am re-learning PHP & Mysql.  I am using a book of tutorials and am having a problem with this section of code. The problem is that the "is_file" test always fails.  If I remove the test then the image files (whose name we're pulling from the database) display as intended.  The constant "GW_UPLOADPATH" is correct as it correctly displays the default image when the "is_file" test fails. I'm sure it's something simple I'm just overlooking.  Thanks for the help

Code: [Select]
<?php
     //Define the upload path and maximum file size constants
   define('GW_UPLOADPATH', 'images/');
  // Connect to the database 
  $dbc = mysqli_connect('localhost', 'testing', '12345', 'guitarwars');

  // Retrieve the score data from MySQL
  $query = "SELECT * FROM guitarwars";
  $data = mysqli_query($dbc, $query);

  // Loop through the array of score data, formatting it as HTML 
  echo '<table>';
  while ($row = mysqli_fetch_array($data)) { 
    // Display the score data
    echo '<tr><td class="scoreinfo">';
    echo '<span class="score">' . $row['score'] . '</span><br />';
    echo '<strong>Name:</strong> ' . $row['name'] . '<br />';
    echo '<strong>Date:</strong> ' . $row['date'] . '</td>';
   if (is_file($row['screenshot']) && filesize($row['screenshot']) > 0) {
   echo '<td><img src="' . GW_UPLOADPATH . $row['screenshot'] . '" alt="Score Image" /></td></tr>';
   }
   else {
    echo '<td><img src="' . GW_UPLOADPATH . 'unverified.gif" alt="Unverified Score" /></td></tr>';
   }
  }
  echo '</table>';

  mysqli_close($dbc);
?>

Hi all

My code give this:

<b>Warning</b>:  file_exists(): open_basedir restriction in effect. File(/tmp) is not within the allowed path(s): (/home/clients/........

I get the tmp folder and check for its existanse and whether it is writeable

$t=sys_get_temp_dir();
writelog("t=$t");
if(file_exists($t)) writelog("t1=YES"); else writelog("t1=NO");
if(is_writable($t)) writelog("t2=YES"); else writelog("t2=NO");

Both gives no which is fine, I can process that. I do it to avoid the output above, but I still get that.

How should I check for allowed paths?

This runs on several systems where I cannot access php.ini or other system stuff.

 

class curl2{

    private $curl_init; 
    private $CURLOPT_URL;

    public function connect(){ 
       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

    }

    public function setUrl($url = null){
       $this->CURLOPT_URL = $url;
       curl_setopt($this->curl_init, CURLOPT_URL, $this->CURLOPT_URL);
    }

    public function execute(){

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();



It display a blank page like attachment result1.jpg, but if I move the
$fp = fopen("curl2.txt", "w"); 
curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);
from function debug() and join it with function execute()
like this:
  public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }

it return me Linuxformat content ( expected result ) like result2.jpg

below is the working code :
class curl2{

    private $curl_init; 
    private $CURLOPT_URL;

    public function connect(){ 
       $this->curl_init = curl_init(); 
    }

    public function debug(){
 
       curl_setopt($this->curl_init, CURLOPT_VERBOSE, TRUE);
      

    }

    public function setUrl($url = null){
       $this->CURLOPT_URL = $url;
       curl_setopt($this->curl_init, CURLOPT_URL, $this->CURLOPT_URL);
    }

    public function execute(){
       $fp = fopen("curl2.txt", "w"); 
       curl_setopt($this->curl_init, CURLOPT_STDERR, $fp); 
       curl_setopt($this->curl_init, CURLOPT_RETURNTRANSFER, TRUE);

       $out = curl_exec($this->curl_init);
       curl_close($this->curl_init);

       return $out;
    }
}

$curl2 = new curl2;
$curl2->connect();
$curl2->setUrl("http://www.linuxformat.co.uk");
$curl2->debug();
echo $curl2->execute();

 
Why I couldn't split "CURLOPT_STDERR, CURLOPT_RETURNTRANSFER" with "curl_exec"
