 My Week 10 Basic Assignment
http://members.lycos.co.uk/jef...wan/class10.php

The delete Switch is just for further purpose. No use now.



<?
$error = 'Sorry, I could not open this file! Check that the permissions are set properly for this file and that you used the correct absolute path to the file.';
$file_contents = file('filemail');
sort($file_contents);
$sizeof = count($file_contents);

$action=$_REQUEST['action'];
$todelete=$_REQUEST['todelete'];
$user=$_REQUEST['user'];
$email=$_REQUEST['email'];

switch ($action)
{
case 'add':
echo ("Enter add Mode<br>");
if($filehandle = fopen("filemail", "a"))
{
fputs($filehandle, "$user:$email\n");
fclose($filehandle);
print("Successfully added <b>$user</b> to the file<br>");
} else {
echo($error);
}
echo ("Click <a href=".$_SERVER['PHP_SELF'].">Here</a> to Refresh!<br>");
exit;
break;
case 'delete':
echo ("Enter Delete Mode<br>");
if($filehandle = fopen("filemail", "w"))
{
for($i=0; $i < $sizeof; $i++)
{
if($file_contents[$i] != $email)
{
fputs($filehandle, "$file_contents[$i]");
} else
{
$flag = 1;
}
}
fclose($filehandle);
if($flag)
{
print("Successfully deleted <b>$email</b> from the file<br>");
} else
{
print("I didn't find $todelete to delete from file");
}
} else
{
echo($error);
}
echo ("Click <a href=".$_SERVER['PHP_SELF']."> Here to Refresh!<br>");
exit;
break;
default:
?>
<table summary="OutPut Name">
<tr>
<td>Name</td>

</tr>
<?
for($i=0; $i < $sizeof; $i++)
{

echo ("<td><a href='mailto:".$user[1]."'>".$user[1]."</a></td>");
echo ("</tr>");
}
?>
</table>

 In the course text, on the "A form to add to and delete members from the existing file" section, i found this line:

<input type="action" value="delete">

isnt it <input type="hidden" name="action" value="delete"> ?

were you in a rush? :)

 ok forget what i said, i got tottaly lost with that code:


<?
$file_directory = '/usr/home/tdavid';
$error = 'Sorry, I could not open this file! Check that the permissions are set properly
for this file and that you used the correct absolute path to the file.';
$file_contents = file("$file_directory/.htpasswd");
sort($file_contents);
$sizeof = count($file_contents);
if(($action != "delete") OR ($action != "add")) {
?>
<form method=POST action="<? echo($PHP_SELF); ?>">
<input type="action" value="delete">
<select name="todelete">
<?
for($i=0; $i < $sizeof; $i++) {
$user = explode(":", $file_contents[$i]);
print("<option value=\"$file_contents[$i]\">$user[0]</option>");
}
?>
</select> <input type="submit" value="Delete User">
</form><br>
<form method=POST action="<? echo($PHP_SELF); ?>">
<input type="action" value="add">
Username: <input type="text" name="user" size=10><br>
Password: <input type="password" name="pwd" size=10> <input type="submit" value="Add New User">
</form>
<?
// start action routine for actual deletion or additon of new members
}
?>



the form part is tottally wrong i beleive, instead of
<input type="action" value="delete">
and
<input type="action" value="add">

it should defenetly be:
<input type="hidden" name="action" value="delete">
and
<input type="hidden" name="action" value="add">

and i was gonna say something about the select dropdown for() loop but i would be dumb cuz its cool :) you could put the explode $file_contents outside the loop tho, if the file is too big it can take a considerable ammount of time to explode as many times as existing names

 I am stuck. I can't get my page to display the data until submit is hit a second time, or the page is refreshed!? * Please help me *

Incidentally, when 'refresh' is hit, the same data is resubmitted. Whats a way around that?

Code is not error checked..yet...

 Hi Lestat - as I just showed you in the irc.scriptschool.com #scriptschool chat. The $sizeof variable is being assigned a value before you add a new item to it so the for loop isn't reaching the last item in the array (the newest item).

 OK got it. Somebody *wink* mentioned to me that my $sizeof count was up in the beggining of the code. This was causing the table to be output from the original data, not the new appended data. Its always something small!


<?
// [ DIR PATH, & CONTENTS ]
$action = $_POST['action'];
$email = $_POST['email'];
$name = $_POST['name'];
$path_to_dir = '/my/path/'; // path to directory
$error = "Whoops, Can't read/write or access the file for some reason<br>"; // error msg

// [ ADD ENTRY TO FLAT FILE ]
if(($name == " " || $email == " ") || ($name == "" || $email == "")){ // Disallow blank or empty string entries
print("<b>Invalid Entry</b>, Please go back and check your entry");
}else{
if(ereg("([[:alnum:]\.\-]+)(\@[[:alnum:]\.\-]+\.+)", $email)){ // proceed ONLY if email is valid format
if($_POST['action'] == "true"){
if($filehandle = fopen($path_to_dir . "email.txt", "a")){ // Open the file
fputs($filehandle, $name . ":" . "$email\r\n"); // Append the contents
print("Added,<b> $name </b>with the address<b> $email </b>to the flat file"); // Print confirm
fclose($filehandle);
}else{
echo($error);
}
}
}else{
print("Sorry, <b>$email</b>, is not a correct email format,<br>Please go back and correct the address");
}
}

// [ READ & OUTPUT FILE CONTENTS ]
$file_contents = file($path_to_dir . "email.txt"); // contents of the file in the dir
$sizeof = count($file_contents); // count how many lines of content are in the flat file
sort($file_contents); // alphabetically sort contents
print("<table border=1> <tr><td><b>Name:</b></td><td><b>Email:</b></td></tr>");
if($filehandle = fopen($path_to_dir . "email.txt", "r")){
while(!feof($filehandle)){
$file_contents[] = fgets($filehandle);
}
for($i=0; $i<$sizeof; $i++) {
$entry=explode(":", $file_contents[$i]);
print ("<tr><td>" . $entry[0] . "</td><td>" . $entry[1] . "</td></tr>");
}
print("</table><br>");
}else{
print($error);
}
?>

<table border="0" align="left">
<form method="POST" action="http://www.timslan.com/scriptskewl/week10/wk10basic.php">

 Link to my email list script for week 10: http://www.algore.org/~admin/mailfile.php

And the code:


<?
// Write a script to add sorted email addresses and names
// to a file and with the same script how to retrieve all
// the information and print to browser the name and email
// address in a table.

$file_directory = '/Users/admin/Sites/';
$error = 'I could not open the email file! Verify permissions are correct and the absolute path to the file.';
$file_contents = file("$file_directory/emaillist.txt");
sort($file_contents);
$sizeof = count($file_contents);

// if they aren't adding a new address, show the form
if($_POST['action'] != "add") {
?>
<html><body>
<i>You may add your name to our public list below:</i> <br />
<form method=POST action="<? echo($PHP_SELF); ?>">
<input type="hidden" name="action" value="add"><br />
Your Name:
<input type="text" name="name" size="20"><br />
Email Address:
<input type="text" name="address" size="18"><br />
<input type="submit" value="Add New Email">
</form> <br />

<i>Current members:</i> <br /> <br />
<!-- Begin Table of email addresses -->
<table border="1">
<tr><td><b>NAME:</b></td><td><b>EMAIL:</b></td></tr>
</body>
</html>
<?
for($i=0; $i < $sizeof; $i++) {
$email = explode(":", $file_contents[$i]);
print("<tr>");
print("<td>".$email[0]."</td>");
print("<td>".$email[1]."</td>");
print("</tr>");
}

print ("</table>");
// add the new email address to the file
} else {
if ($_POST['action'] == "add") {
if($filehandle = fopen("$file_directory/emaillist.txt", "a")) {
fputs($filehandle, $_POST['name'].":".$_POST['address']."\n");
fclose($filehandle);
print("Successfully added <b>".$_POST['name']."</b> to the file");
} else {
echo($error);
}
}
}
?>

 i thought this was very tough. took me all day to figure out the explode and how to open and write to the files. anyways, here it is



<?
$theform="<form method=\"post\" action=\"$PHP_SELF\">
<input type=\"hidden\" name=\"form\" value=\"true\">
name: <input type=\"text\" name=\"yourname\"><br>
email: <input type=\"text\" name=\"youremail\"><br>
<input type=\"submit\" value=\"Submit\">";
$theerror="Bad info or something. check script and try again";
$file_directory="/home/rlang/domains/bigtitsfinder.com/public_html/testing";
if($form=="true"){
$info_to_add="$yourname|$youremail\n";
if($file_content=fopen("$file_directory/info.txt","a")){
fputs($file_content, $info_to_add);
fclose ($file_content);
print("info added<br><a href=\"$PHP_SELF?infoadded=true\">click here</a> to see the info.");
}else{
print("$theerror");
}
}elseif($infoadded=="true"){
if($file_content=file("$file_directory/info.txt")){
sort($file_content);
print("<table border=\"1\">");
$countinfo=count($file_content);
for($i=0; $i<$countinfo; $i++){
$user = explode("|", $file_content[$i]);
print("<tr><td width=\"300\">name: $user[0]</td><td width=\"300\" bgcolor=\"#aaaaaa\">email: $user[1]</td></tr>");
}
}else{
print("$theerror");
}
}else{
print("$theform");
}
?>
