[SOLVED] Quick help...

[trecool999]

How could I add a filter to this script:

<?
    echo "<form>";
    echo "<select name='Files'>";
    $dirpath = "../Text_Editor/";
    $dh = opendir($dirpath);
       while (false !== ($file = readdir($dh))) {
          if (!is_dir("$dirpath/$file")) {
           echo "<option value='$file'>" . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . '</option>';
   }
}
     closedir($dh); 
echo "</select>";
echo "</form>";
?> 

 

So that you can only see .txt files?

See if changing:

while (false !== ($file = readdir($dh))) {
          if (!is_dir("$dirpath/$file")) {
           echo "<option value='$file'>" . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . '</option>';
   }

to this works:

while (false !== ($file = readdir($dh)))
{
    echo substr($file, -4, 4) . "<br />\n";

    if(substr($file,  -4, 4) == '.txt')
    {
        if (!is_dir($dirpath . '/' . $file))
        {
            echo '    <option value="' . $file . '">' . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . "</option>\n";
        }
    }
}

Argh! I just found out the original script doesn't work now either...

 

I'll see to the problem in a few minutes.

Rety my code again. I had major problems with it. I recoded and tested and you script works fine.

<?php

echo "<form>
  <select name=\"Files\">\n";

$dirpath = "./";

$dh = opendir($dirpath);

while (false !== ($file = readdir($dh)))
{
    if(substr($file,  -4, 4) == '.txt')
    {
        if (!is_dir($dirpath . '/' . $file))
        {
            echo '    <option value="' . $file . '">' . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . "</option>\n";
        }
    }
}
closedir($dh);

echo "</select>
</form>";

?>

Sweetness !

 

Works like a charm, do you know of any way to use 'onClick' with each option? If not, don't worry and thanks!

[wildteen88]

You will want to add it to the select tag. So if you do this:

 

echo "<form name=\"file\">
  <select name=\"Files\" onchange=\"document.file.submit();\">\n";

When you choose an option it will submit the form.

[trecool999]

No, what I meant was, if you click on one of the options, it will copy that option into the text box, but I just figured that out, so... yeah, s'all good.

 

I stuck this:

<?php

echo "<form>
  <select name=\"Files\">\n";

$dirpath = "./";

$dh = opendir($dirpath);

while (false !== ($file = readdir($dh)))
{
    if(substr($file,  -4, 4) == '.txt')
    {
        if (!is_dir($dirpath . '/' . $file))
        {
            echo '    <option value="' . $file . '" onClick="form1.Title.value += \'' . $file . '\'">' . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . "</option>\n";
        }
    }
}
closedir($dh);

echo "</select>
</form>";

?>

 

In an include file.

 

New problem

 

When it copies it into to the box, it brings the .txt extension with it, even though it uses the exact same variable ($file) as the display in the list does... any solution? Or is there any way I could cut it out when it processes after submission?

[wildteen88]

It is bescause you are passing it with unmodified value for the file variable. But then later on you modify the value on the variable to remove the extension. Simple change this:

            echo '    <option value="' . $file . '" onClick="form1.Title.value += \'' . $file . '\'">' . htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file))) . "</option>\n";

to this:

            $f = htmlspecialchars(ucfirst(preg_replace('/\..*$/', '', $file)));
            echo '    <option value="' . $file . '" onClick="form1.Title.value += \'' . $f . '\'">' . $f . "</option>\n";

Woohoo!

 

Thanks, that's all I needed to know.

 

Now, over the the Javascript forum!
