IMAGE display table

[agentjozef]

I have the code below displaying images and image names. I want these to display in a table 2 rows high by the needed number of columns to show all the images in the directory. I have no idea what to do. What I am getting now is a single column with each image in its own row.

<?php

$path = "./uploaded/";

$dir_handle = @opendir($path) or die("Unable to open folder");

while (false != ($file = readdir($dir_handle)))

{

if($file == "index.php")

continue;

if($file == ".")

continue;

if($file == "..")

continue;

//show in a table 2 rows by required/needed number of columns

echo'<div>';

echo '<table border="1">';

echo "<img src='$path/$file' alt='$file'>"."<img src='$file' alt='$file'>";

echo'</table>';

echo '<div>';

}

?>

[agentjozef]

sorry the above code is not what I have it is this:

<?php

$path = "./uploaded/";

$dir_handle = @opendir($path) or die("Unable to open folder");

while (false != ($file = readdir($dir_handle)))

{

if($file == "index.php")

continue;

if($file == ".")

continue;

if($file == "..")

continue;

//show in a table 2 rows by required/needed number of columns

echo'<div>';

echo '<table border="1">';

echo "<td><img src='$path/$file' alt='$file'><br />"

echo "<img src='$file' alt='$file'></td>";

echo'</table>';

echo '</div>';

}

?>

You should do something like this:

 

 

Put only images and some table elements in a loop:

 

echo '<table>';

$counter = 0;

 

while(count($image) != $counter){

      echo "<tr>";

      echo "<td>". $image[$counter] . "</td>";

      ++$counter;

      echo "<td>" . $image[$counter] . "</td>";

      echo "</tr>";

      ++$counter;

}

 

echo '</table>';

Sorry, but I am new to this and I do not understand what you are telling me.

Could you elaborate please?

[agentjozef]

My code now looks like what is below. It seems that all of the images are being placed one on top of the other in one cell.

 

<?php

$path = "./uploaded/".$_SESSION['sec'];

$dir_handle = @opendir($path) or die("Unable to open folder");

while (false != ($file = readdir($dir_handle)))

{

if($file == "index.php")

continue;

if($file == ".")

continue;

if($file == "..")

continue;

//show in a table 2 rows by required/needed number of columns

 

$aaa = ("<td><img src='$path/$file' alt='$file'><br />"."<img src='$file' alt='$file'></td>");

 

}

echo '<table border="1">';

echo '<td>'.$aaa.'</td>';

echo'</table>';

[litebearer]

curious ... how many potential images will there be?

[agentjozef]

A dynamic amount.

[litebearer]

1. "dynamic" = will vary - for example... 500 images would result in 250 images wide - I am certain you might not like that.

 

2. Did you notice that Ivan's code puts the echo INSIDE the loop'; whereas your only echoes once OUTSIDE the loop?

    I know what dynamic means. I would be extremely happy with such a result.

 

2. Did you notice that Ivan's code puts the echo INSIDE the loop'; whereas your only echoes once OUTSIDE the loop?

    With all due respect, did you notice my comment after Ivan's saying I do not understand him?

 

Anyhow, I have changed the code to look like below, but still there is only one cell appearing. My expectation (although not what I want) from this was to have one row with dynamic columns - I want 2 rows. But, unfortunately that is not even happening.

 

<?php

$path = "./uploaded/";

$dir_handle = @opendir($path) or die("Unable to open folder");

while (false != ($file = readdir($dir_handle)))

{

if($file == "index.php")

continue;

if($file == ".")

continue;

if($file == "..")

continue;

//show in a table 2 rows by required/needed number of columns

echo '<table border="1">';

$aaa = ("<td><img src='$path/$file' alt='$file'><br />"."<img src='$file' alt='$file'></td>");

 

}

 

echo $aaa;

echo'</table>';

?>

[litebearer]

try (not proof read not tested)...

<?PHP
echo '<table border="1">';
echo "<tr>";
$images = glob("./uploaded/{*.jpg,*.gif,*.png}");
$count = count($images);
$half = ceil($count/2);
$half1 = ($count/2);
$i=0;
while($i<$half){
?>
<td><img src="<?PHP echo $images[$i]; ?>"></td>
<?PHP
$i++;
}
echo "</tr><tr>";

$i=$half;
while($i<$count){
?>
<td><img src="<?PHP echo $images[$i]; ?>"></td>
<?PHP
$i++;
}
if($half1 != $half) {
echo "<td></td>";
}
echo "</tr>";
echo "</table>";
?>

[litebearer]

Ok (6 cups of coffee later); tested the glob, can't get it quite right sooooooo....

 

tested this

<?php
$path = "images/";
$dir_handle = @opendir($path) or die("Unable to open folder");
while (false !== ($file = readdir($dir_handle))) {
if($file == "test898.php" OR $file == "." OR $file == "..")
	continue;
$images[] = $path . $file;
}
closedir($dir_handle);
$count = count($images);
$row1 = ceil($count/2);
$row2 = $count - $row1;
$display1 = "<table border='1'><tr>";
for($i=0;$i<$row1;$i++) {
$display1 = $display1 . "<td><img src='" . $images[$i] . "'</td>";
}
$display1 = $display1 . "</tr>";
if($count>1) {
$display1 = $display1 . "<tr>";
for($i=$row1;$i<$count;$i++) {
	$display1 = $display1 . "<td><img src='" . $images[$i] . "'</td>";
}
$display1 = $display1 . "</tr>";
}
$display1 = $display1 . "</table>";
echo $display1;
?>

Thank you for your help litebearer! It is truly appreciated. Your script does what I wanted.

I am referring to your untested one (I noticed you sent a message while I was typing this.)

Nevertheless, I got out of that mud pit and into another

I went ahead and changed and complicated your script (2) above by attempting to add a function to delete files.

But to no surprise, it does not function. Interestingly, it does not give me the error message associated with not deleting either.

I would like some help on getting this sucker to delete selected files. Also, in what way can I get just the file names to show rather than the whole path?

Here is the script:

 

<html>

<body>

<?php

{

    foreach($_POST['file[$i]'] as $file)

    { 

        unlink($file) or die("Failed to delete file");

    }

    header("location: " . $_SERVER['REQUEST_URI']); //this should refresh the page leaving only undeleted files

}

?>

<form name="form1" method="post">

<?php

echo '<table border="1">';

echo "<tr>";

$file = glob("./uploaded/*.*");

$count = count($file);

$half = ceil($count/2);

$half1 = ($count/2);

$i=0;

while($i<$half){

echo ("<td><img src=".$file[$i]."><br />"."<input type='CHECKBOX' name='file' value='$file[$i]'>".$file[$i]."</td>");

$i++;

}

echo "</tr><tr>";

 

$i=$half;

while($i<$count){

echo ("<td><img src=".$file[$i]."><br />"."<input type='CHECKBOX' name='file' value='$file[$i]'>".$file[$i]."</td>");

$i++;

}

if($half1 != $half) {

echo "<td></td>";

}

echo "</tr>";

echo "</table>";

 

//if directory is empty do not show delete button   

$dirPath = "./uploaded";

$handle = opendir($dirPath);

$c = 0;

while ($file = readdir($handle)&& $c<3) {

    $c++;

}

if ($c>2) {

echo '<input type="submit" name="Delete" value="Delete">';

} else {

  closedir($dir_handle);

}   

echo '</form>';

?>

</body>

</html>

In the future, when posting code, enclose it within the forum's

 . . . 

BBCode tags.

[litebearer]

As to file name sans path, review this and see if you can incorporate it (untested)

 

while($i<$half){
$path_parts = pathinfo($file[$i]);
$image_name = $path_parts['basename']
?>
<td>
<img src="<?PHP echo $file[$i]; ?>">
<br />
<input type='CHECKBOX' name="cbox[<?PHP echo $i; ?>]" value="<? echo $file[$i]; ?>"
<?PHP echo $image_name; ?>
</td>
<?PHP
$i++;
}

[agentjozef]

Yes lightbearer, that did the trick. Thank you.

Here is what that section looks like now.

 

<?php
echo '<table border="1">';
echo "<tr>";
$file = glob("./uploaded/*.*");
$count = count($file);
$half = ceil($count/2);
$half1 = ($count/2);
$i=0;

while($i<$half){
$path_parts = pathinfo($file[$i]);
    $image_name = $path_parts['basename'];
echo "<td><img src=".$file[$i]."><br />"."<input type='CHECKBOX' name='cbox[$i]' value='$file[$i]'>".$image_name.'</td>';
$i++;
}
echo "</tr><tr>";

$i=$half;
while($i<$count){
$path_parts = pathinfo($file[$i]);
    $image_name = $path_parts['basename'];
echo "<td><img src=".$file[$i]."><br />"."<input type='CHECKBOX' name='cbox[$i]' value='$file[$i]'>".$image_name.'</td>';
$i++;
}
if($half1 != $half) {
echo "<td></td>";
}
echo "</tr>";
echo "</table>";

[agentjozef]

I figured the delete function out.

At the top, $_POST['file[$i]']

Inside [] should be 'cbox'.
