I'm using a PHP webpage to give me a list of all files with a .264 extension in a specific folder. The file is then selected and sent to a command to playback the video on a display attached to the computer.
I'm having difficulties trying to get the radio buttons to maintain their values, so that when they are selected and the form button is pressed, they do not know their values and are therefore not able to execute the script.
I know the script works, because I tested it with just a fill-in-the-blank type form and had no problems.
Now I'm listing the files with a radio button to select the file and submit it to the form to play, but it isn't working as I had hoped.
I've looked around and tried to figure it out. I'm not sure if I need to use a linked list or something instead of an array. This is my first time doing php coding, so I'm not sure where I should start to try to resolve this.
<?php
$FileCount = 0;
$currentdir = '/data/'; //Location of Hard Drive
$dir = opendir($currentdir);
$array = array();
echo '<ul>';
while ($File = readdir($dir)){
//if (is_file($file))
$ext = pathinfo($File, PATHINFO_EXTENSION);
if ($ext == '264'){
$array[] = "$File";
echo "<INPUT class='radio' type='radio' name='FileName' value='$File' /> <span>$File</span><p>";
$FileCount++;
}
}
echo '<form action="test.php" method = "post">';
echo "<INPUT TYPE = 'Submit' name = 'FormSubmit' value = 'Submit'>";
echo '</form>';
if ($_POST['FormSubmit'] == "Submit")
{
echo $_POST["FileName"];
}
Nothing returns with this code. Any help would be great. Thanks.
If you want the values of the radio button controls to be sent along with the form post, then the controls themselves must be children of the form element.
<form method = "post" action = "">
<?php while ($File = readdir($dir)) {
if(pathinfo($File, PATHINFO_EXTENSION) == '264')) { ?>
<input type = "radio" ... >
<?php
}
}
?>
<input type = "submit" value = "Submit" name = "FormSubmit">
</form>
As you have it now, the radio buttons exist outside of the form, so they are not part of the form.
echo '<form action="test.php" method = "post">';
add this code below
while ($File = readdir($dir)){

First, forgive me if this is an overly pedantic question. I have searched trying to find answers but perhaps I'm using the wrong search terms.
Trying to use an INI file for a simple PHP application, where there is an admin page to allow application options to be easily changed. I'm able to read in the ini file with no issue, problem I'm coming across is on the write - if any boolean values are false, they won't get put into the _POST and as such don't get written back into the ini file. Here's my sample:
settings.ini file:
[Site options]
bRequireLegal['Require NDA before badge print'] = true ;
bCollectVehicleInfo['Collect vehicle information'] = false;
bShowAdditionalMessageBeforeBadgePrint['Show badge printing message'] = true;
[Company info]
companyname['Company Name'] = 'The Company, Inc.' ;
Code to read in the ini file (settings.php):
$filepath = 'settings.ini'; //location of settings file
$settings = parse_ini_file($filepath, true, $scanner_mode = INI_SCANNER_TYPED);
//pull everything in ini file in as variable
foreach($settings as $section=>$options){
foreach($options as $option=>$values){
foreach($values as $descriptor=>$value){
if(is_bool($value) === true) {
${htmlspecialchars($option)} = +$value;
}
else ${htmlspecialchars($option)} = $value;
}
}
}
And finally, the options setting page:
<?php
include 'settings.php';
//after the form submit
if($_POST){
$data = $_POST;
update_ini_file($data, $filepath);
}
function update_ini_file($data, $filepath) {
$content = "";
//parse the ini file to get the sections
foreach($data as $section=>$options){
//append the section
$content .= "[".$section."]\r\n";
//append the values
foreach($options as $option=>$values){
$content .= $option;
foreach($values as $descriptor=>$value){
$content .= "['".$descriptor."'] = '".$value."';\r\n";
}
}
$content .= "\r\n";
}
if (!$handle = fopen($filepath, 'w')) {
return false;
}
$success = fwrite($handle, $content);
fclose($handle);
return $success;
}
?>
<html>
<body>
<?php
?>
<div class="container-fluid">
<form action="" method="post">
<?php
foreach($settings as $section=>$options){
echo "<h3>$section</h3>";
//keep the section as hidden text so we can update once the form submitted
echo "<input type='hidden' value='$section' name='$section' />";
//print all other values as input fields, so can edit.
foreach($options as $option=>$values){
foreach($values as $descriptor=>$value){
if(is_bool($value) === true) {
echo "<p>".$descriptor.": <input type='checkbox' name='{$section}[$option][$descriptor]' ".(($value===true)?" checked":"")." /></p>";
} else
echo "<p>".$descriptor.": <input type='text' name='{$section}[$option][$descriptor]' value='$value' />"."</p>";
}
}
echo "<br>";
}
?>
<input type="submit" value="Update INI" />
</form>
</div>
</body>
</html>
Any help would be greatly appreciated!
In your update_ini_file() function, replace this:
$content .= "['".$descriptor."'] = '".$value."';\r\n";
with
$content .= "['".$descriptor."'] = '".($value ? 'true' : 'false')."';\r\n";
This will cause it to write the strings 'true' and 'false' instead of literal Boolean values. See How to Convert Boolean to String
Edit to add:
I think you're generating your checkboxes incorrectly:
<input type='checkbox' name='{$section}[$option][$descriptor]' ".(($value===true)?" checked":"")." />
This will cause the 'true' boxes to be checked, but they will still lack a value (and thus will not be transmitted to the server when the form is submitted). You should change that code to:
<input type='checkbox' name='{$section}[$option][$descriptor]' value='1'".(($value===true)?" checked":"")." />
In other words, all checkboxes should have a value of '1', but the way the browser works, only those which are checked will be submitted.
Edit to add:
Checkboxes that are not checked will not get submitted. That explains why you are not seeing any output for values that are 'false': they simply don't get submitted. When you loop through $data (which comes from $_POST), it is missing those unchecked (and thus 'false') checkboxes.
Using a solution found here: POST unchecked HTML checkboxes
Change this:
echo "<p>".$descriptor.": <input type='checkbox' name='{$section}[$option][$descriptor]' ".(($value===true)?" checked":"")." /></p>";
to this, which includes a hidden field that has the value '0', which will get submitted even if the corresponding checkbox is unchecked:
echo "<p>".$descriptor.": <input type='hidden' name='{$section}[$option][$descriptor]' value='0'><input type='checkbox' name='{$section}[$option][$descriptor]' ".(($value===true)?" checked":"")." /></p>";
However, this has its own set of potential problems, specifically when a checkbox is checked, you will send two identically named fields: one with a '0' value and the other with a '1' value. This is explained in the link above, and is left as an exercise for you to solve (or ask for further details on) if my answer doesn't work.
The file has a 2 texboxes submit button when it is tapped the data is put into the newly created file.Each new created file
I have file j.php that creates a texfile question.$myDate.txt creates a new txt file with a unique name and $question1 represents the question and it is put in the textfile data as the first element the sign "," splits $question1 and $question2. The variable $question2 represents the answer. And is put the second element in the text file.
The second file questions.php opens instntly after the button is submitted the file is supposed the read adn split the data of the text file and read it and dispay it once the texfile is split into two elements since the text files contains two elements. The first one shows up as a question and the texbox in should be written an answer and the form would be submitted.
But the problem on file 2 it it dosen't read the textfile data. when the text box pops up.
<?php
if(isset($_POST['submit'])) {
$number =$number +1;
$myDate = round(10*microtime(TRUE));
$result ="question".$myDate.".txt";
$question1 = $_POST['name'];
$question2 = $_POST['age'];
$file = fopen( $result, "w+" ) or die( "file not open" );
$s = $question1 . "," . $question2 . "\n";
fputs($file, $s)or die("Data not written");
// Here - redirect to questions.php to display the contents.
header('Location: questions.php');
die;
}
else{
echo
'<center>
<form action = "j.php" method = "post">
<br>Question you want ask the person <input type = "text" name="name"> <br>
<br>Answer<input type = "text" name = "age"><br>
<input type = "submit" name = "submit" value = "Make Question">
</form>
</center>';}
?>
<?php
$myDate = glob("*.txt");
$myFile = "question".$myDate."txt";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
fclose($fh);
$arr =explode(",",$theData);
$x=$arr[0];
$y = $arr[1];
$text = $_POST["name"];
$text = true;
if($_POST['submit']) {
$text = $_POST["name"];
if ( $text ==$y) {
echo "<font color = 'red'>Your answer is incorrect</font>";
} else {
echo "answer not correct";
}
}
?>
<center>
<form method = "post">
<?php echo $x ?> <input type = "text" name="name"> <br>
<input type = "submit" name = "submit" value = "Submit answer">
</form>
</center>
\\expected output the texfile being read and next to the text box the question popped upp\\
I have a problem in using $_FILES and $_POST at the same the because I have a form to upload an image and some data bus when I use one of them it works but when I used the other one id doesn't work.
my code is :

I don't know what is the problem, any help??
Everything inside that if (isset($_FILES['picName'])and isset($_POST['submit'])) doesn't work because the superglobal $_FILES is probably not having a key named picName. To check this out, try var_dump-ing the $_FILES, like var_dump($_FILES);
By the output of the var_dump you'd get to know if there is any content inside $_FILES. And if it is populated, just see what the key name is and, access the file by using that key.
But if the array is empty, there may be some mis-configurations in PHP, or APACHE.
One possible fix would be setting file_uploads = On in the ini file for php.
Hope it helps!
You have to validate the size of the file if you want to do an isset. I don't know if this is works, but the better way for do that is check first the size for validate if isset or was send to the server.
Then, in your <form method='post' action='uplaodex.php' enctype='multipart/form-data'> you have to create another PHP file with the name uplaodex.php where you'll send al the data. So, your code with be like the below code following and considering the step 1. This will be your uploadex.php
$name_file = $_FILES['picName']['name'];
$type = $name_file['type'];
$size = $name_file['size'];
$tmp_folder = $name_file['tmp'];
$usName = trim($_POST['usName']);
$usUsername = trim($_POST['usUsername']);
$usPass = trim($_POST['usPass']);
$usEmail = trim($_POST['usEmail']);
if ( $size > 0 ) {
//REMOVE another slash images//
$name = "images/" . $name_file; //unix path uses forward slash
//'filename' index comes from input type 'file' in the form above
//
//move uploaded file from temp to web directory
if ( move_uploaded_file($tmp_folder, $name) ) {
// Create the file DO and populate it.
include 'Do_profile.php';
$file = new Do_profile();
$file->FileName = $name; //$name is initialised previously using $_FILES and file path
$file->FileSize = $size;
$file->Type = $type;
$file->usName = $usName;
$file->usUsername = $usUsername;
$file->usPass = $usPass;
$file->usEmail = $usEmail;
if ($file->save()) {
//USE PRINTF
printf('<h1> Thankyou </h1><p>Image stored successfully</p><br>
<p>Uploaded file: %s</p>. <img src="%s" height="200" width="200" />',
$name_file, $name );
#WHAT IS $fileId? In which moment was define?
//echo '<br><a href="Display.php?id=' . $fileId . '">Display image ' .
$file->FileName . '</a>';
}
else
echo '<p class="error">Error retrieving file information</p>';
}
else {
echo '<p class="error"> Oh dear. There was a databse error</p>';
} //ENDIF OF if (move_uploaded_file($_FILES['picName']['tmp_name'], $name))
} //ENDIF OF if ( $size > 0 )
#ELSE OF YOUR if ( $size > 0 )
else {
//error handling in case move_uploaded_file() the file fails
$error_array = error_get_last();
echo "<p class='error'>Could not move the file</p>";
// foreach($error_array as $err)
// echo $err;
}
I solved the problem, you can't perform $_FILES and $_post at the same time or one of them inside the other.
start with $_Post and then $_FILES and outside the $_FILES run your saving function
thats it
I have a form which takes two values. One takes a .txt file, the file at which some links are hard coded and a text field which takes a url. When I press submit it takes that url and checks on every link that is on *.txt file. Hope you understand what I am saying if not then please comment I will clarify it. Now I have problems. My code does not work until the file at which links are, is not at my server. I don't how to handle this problem. I have done my search, I also try mysql but that is not ok for me. My script is this:
Enter your file :<input type="file" name="ufile" />
Enter your site name :<input type="text" name="utext" />
<input type="submit" value="Check" />
Now, my php script is this:
$needle = $_POST['utext'];
$file = $_FILES['ufile'];
$new = file($file, FILE_IGNORE_EMPTY_LINES | FILE_SKIP_EMPTY_LINES);
$new = array_map('trim', $new);
echo 'Total entries are: '.count($new).'<br />';
$found = array();
$notfound = array();
foreach ($new as $check) {
echo "<table border='1'><tr>";
echo "<td>Processing</td> <td>", $check,"</td></tr>";
$a = file_get_contents($check);
if (strpos($a, $needle)) {
echo "<td><font color='green'>Found:</font></td>";
$found[] = $check;
} else {
echo "<td><font color='red'>Not Found</font></td>";
$notfound[] = $check;
}
echo "</tr></table>";
}
echo "Matches ".count($found)."<br />";
echo "Not Matched ".count($notfound);
Is there any reason you never read the documentation about how PHP handles uploads in first place? That would make clear that $_FILES['ufile'] is array, so your code cannot work. If you really want to continue writing code without understanding it first, then replace:
$file = $_FILES['ufile'];
with
$file = $_FILES['ufile']['tmp_name'];
I have the following HTML form:
<form action='delete.php' method='POST'>
<table>
<div class = '.table'>
<?php
$dir = '../uploads/store/';
$newdir = ereg_replace('\.','',$dir);
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
if (!preg_match('/^(\.(htaccess|\.)?|index\.html)/',$file)) {
echo "<tr><td><font color = 'white'><a href='$newdir$file'>$file</a></font></td>";
echo "<td><input type='submit' value ='Delete'></td></tr>";
echo "<input align='right' type='hidden' value='$file' name='file'>";
}
}
closedir($dh);
}
}
?>
</div>
</table>
</form>
Which links to the following PHP script:
<?php
session_start();
$file = $_POST['file'];
$dir = '../uploads/store/';
$file = $dir . $file;
opendir($dir);
if(unlink($file)) {
echo "File sucessfully deleted";
$_SESSION['username'] = 'guitarman0831';
header('Refresh: 2;url=http://www.ohjustthatguy.com/uploads/uploads.html');
} else {
echo "Error: File could not be deleted";
$_SESSION['username'] = 'guitarman0831';
header('Refresh: 2;url=http://www.ohjustthatguy.com/uploads/uploads.html');
}
?>
However, when the Delete button is pressed in the HTML form, the item above the one intended to delete is deleted.
Hope this makes sense.
NOTE: I'm not going for security with these scripts, I'm going to work on that later. It's only me using this service right now.
Your HTML form needs to have the various submit buttons pass the value for $file instead of using hidden fields.
The problem is that all of the hidden fields are POSTed to delete.php when you submit the form. Then, since you haven't used the PHP-friendly HTML array variable syntax, PHP uses only the last of these to set the value of $_POST['file']. If you do a var_dump of $_POST in delete.php, you will see what the POSTed input is.
The easiest thing to do, with your current markup, is just to have each submit button be named file and pass $file as its value. i.e. you could do:
<button name="file" value="example.txt" type="submit">Delete</button>
Alternately, you could use radio buttons or some other markup.
