I'm not even sure if I am writing this code as efficiently as possible but I'm stuck and need help...
HTML
<?php
echo outputDirArray($dir_array, 0, '');
?>
In PHP, I have a function to put my directories into an array:
function dirToArray($dir) {
$result = array();
$cdir = scandir($dir);
foreach ($cdir as $key => $value) {
if (!in_array($value,array('.','..'))) {
if (is_dir($dir . DIRECTORY_SEPARATOR . $value)) {
$result[$value] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
} else {
$result[] = $value;
}
}
}
return $result;
} //Thanks to someone on this site for this function
I then take that array and pass it to another function to output it the way I need it to:
function OutputDirArray(&$arr, $x, $origName) {
$str;
foreach ($arr as $key => $value) {
if($x == 0) $origName = $key;
if (is_array($value)) {
if($x > 0) $str .= '</div>';
$str .= '<div class="infoDiv clearfix"><span class="title">'.$key.'</span><br/>'.OutputDirArray($value, ++$x, $origName).'</div>';
--$x;
} else {
if($x > 0) {
$str .= '<div class="displayImgs"><img src="images/'.$origName.'/'.$value.'"/></div>';
} else {
$str .= '<div class="infoDiv clearfix"><span class="title">Profile Picture</span>
<div class="displayImgs"><img src="images/'.$value.'"/></div></div>';
}
}
}
return $str;
}
My var_dump($dir_array); output:
array(3) { [0]=> string(7) "img1.jpg" ["test1"]=> array(4) { [0]=> string(15) "subimg1.gif" [1]=> string(9) "subimg2.png" [2]=> string(9) "subimg3.jpg" ["test3"]=> array(3) { [0]=> string(15) "subsubimg1.gif" [1]=> string(9) "subsubimg2.png" [2]=> string(9) "subsubimg3.jpg" } } ["test2"]=> array(3) { [0]=> string(15) "subimg1.gif" [1]=> string(9) "subimg2.png" [2]=> string(9) "subimg3.jpg" } }
What am I trying to do here is take in the dir_array and walk through outputting the html code. Everything seems to work fine except for two problems...
1) If I have a subsub directory, $key in <span class="title">'.$key.'</span> outputs the correct key (in my case, test3). However $origName in <img src="images/'.$origName.'/'.$value.'"/> outputs the original key used (test1).
2) I believe because of my subsub dir problem, I am left with an extra </div> after the subsub (test3) outputs.
It's been too long now trying to figure this out, so any help is greatly appreciated.
This is very close to what you want
If you would like me to comment it I would gladly do so.
The code preview looks really nice.
Just a tip, get the html correct before you start to add attributes. It only makes things more complicated.
<?php
function dirToArray($dir) {
$result = array("name" => substr($dir, strrpos($dir, "\\") + 1), "children" => array());
foreach(scandir($dir) as $key => $value) {
if (!in_array($value,array('.', '..'))) {
if (is_dir($dir . DIRECTORY_SEPARATOR . $value)) {
$result["children"][] = dirToArray($dir . DIRECTORY_SEPARATOR . $value);
} else {
$result["children"][]["name"] = $value;
}
}
}
return $result;
}
function OutputDirArray($arr, $origName = ".", $tab = "") {
$str = "$tab<div>$origName</div>";
for($i = 0; $i < count($arr["children"]); $i++) {
$child = $arr["children"][$i];
$name = $child["name"];
$path = $origName . DIRECTORY_SEPARATOR . $name;
if ($child["children"]) {
$str .= "
$tab<div>
" . OutputDirArray($child, $path, "$tab\t") . "
$tab</div>";
} else {
$str .= "
$tab<div><img src=\"images\\$path\"/></div>";
}
}
return $str;
}
echo outputDirArray(dirToArray("path\\to\\file"), "path\\to\\file");
?>
In your function, you have this:
if($x == 0) $origName = $key;
I assume this only sets the original name to the key if you are at level zero, since $x is passed in. Since I'm not sure what exactly you're trying to do here, I'm not sure what the solution should be, but my guess is that you should check the value of $key against the $origName passed in or something instead of $x.
