Example:


<?php

$arr1 = array(1,5,7,6);
$arr2 = array(3,;
$arr3 = array(2,0,6);

$arr_all = array_merge($arr1,$arr2,$arr3);

if($arr_all == array_unique($arr_all))
{
  echo "All values are unique";
}
else
{
  echo "One or more values was identical";
}

?>

Norway OK too...

Try to set up some debugging by echoing id's etc while testing to see if it reveals anything. You are however constantly overwriting the $result during foreach, so the redirection is purely based on the last id delete

New example:

<?php

if(isset($_POST['delete'])){
if(isset($_POST['checkbox'])){

$fail = array();
$ok = array();

foreach($_POST['checkbox'] as $no => $del_id){

  $sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
  $result = mysql_query($sql) or die(mysql_error());
  
  if(mysql_affected_rows() == 1){
    $ok[] = "OK: ".$del_id;
  }
  else{
    $fail[] = "Failed: ".$del_id;
  }
}

if(empty($fail)){
  echo "<meta http-equiv=\"refresh\" content=\"0;URL=index.php\">";
}
else{
  echo "Following id's failed to delete:<br />";
  echo implode($fail, '<br />');
  echo "These id's returned ok and should be deleted:<br />";
  echo implode($ok, '<br />');
}
}
else{
  echo "No rows where selected to be deleted";
}
}

?>

On this part

<?php

if($delete){
for($i=0;$i<$count;$i++){
$del_id = $checkbox[$i];
$sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
$result = mysql_query($sql);
}

// if successful redirect to delete_multiple.php
if($result){
echo "<meta http-equiv=\"refresh\" content=\"0;URL=index.php\">";
}
}

?>

Change to

<?php

if(isset($_POST['delete'])){
foreach($_POST['checkbox'] as $no => $del_id){
$sql = "DELETE FROM $tbl_name WHERE id='$del_id'";
$result = mysql_query($sql);
}
// if successful redirect to delete_multiple.php
if($result){
echo "<meta http-equiv=\"refresh\" content=\"0;URL=index.php\">";
}
}

?>

should get you going

Can't you just run both jobs in the same file ?

Simplified example:
[code]

<?php

$hide_form = false;

if(isset($_POST['submit_preview'])){

echo htmlspecialchars(nl2br($_POST['message']), ENT_QUOTES);

}
elseif(isset($_POST['submit_save'])){

// save posted message

$hide_form = true;
}

if($hide_form == false){

echo <<<_FORM

<form method="post" action="test.php">
<textarea name="message" rows="14" cols="70">$message</textarea>
<input type="submit" name="submit_save" value="Save" />
<input type="submit" name="submit_preview" value="Preview" />
</form>

_FORM;
}

?>

[/code]

...or did i misunderstand you ?

January 29, 2007

Or something like this - example with textfields
[code]

<?php

if(isset($_POST['submit']))
{
$query = "select * from house";
$count = 0;
foreach($_POST as $key => $value){
$value = htmlspecialchars($value, ENT_QUOTES);
if($count == 0): $qq = " WHERE"; else: $qq = " OR"; endif;
if(!empty($value)): $query .= "$qq $key = '$value'"; endif;
$count++;
}
$query .= " order by houseid desc";
$sql = mysql_query($query) or die(mysql_error());

// fetch array, show results

}
else
{
// Each formfield name here, must match the target column names in your table (city,state)
echo <<<_HTML

<form action="search.php" method="post">
<p>City: <input type="text" name="city" /></p>
<p>State: <input type="text" name="state" /></p>
<p><input type="submit" name="submit" value="search" /></p>
</form>

_HTML;
}

?>

[/code]

[b]test@server.co.uk[/b] doesn't pass

[b]test@ser;ver.com[/b] passes

...and so will many many more - you should start checking against a valid range of chars instead of illegal chars when matching.

January 28, 2007

[code]
<?php

$status = mail('me@mydomain.com','my subject','email text',$mailheaders);

if($status == 1)
{
// mail() returned true
}
else
{
// failed
}

?>[/code]

That's about the closest you get to a success-machine

January 28, 2007

Agree on something else being your problem if you have tried all solutions here, but not all of these suggestions work (on my server anyhow)

A simplified collection of the proposed soulutions, just one works IF $title is set as "", two of them works if $title is not defined at all
[code]

<?php

function setup_page1($title = false){
if($title == false) $title = "NO TITLE";
echo $title ."<br />";
}

function setup_page2($title = "Untitled")
{
echo $title ."<br />";
}

function setup_page3($title){
$title = (isset($title) || trim($title) != 0) ? "$title" : "NO TITLE";
echo $title ."<br />";
}

$title = "";
setup_page1($title); // prints "NO TITLE"
setup_page2($title); // prints nothing
setup_page3($title); // prints nothing - but if $title is absent, this one works

?>

[/code]

January 28, 2007

In short: you can't reverse it

January 28, 2007

This should work, look at the examples below:
[code]

<?php

function setup_page($title = false){
if($title == false) $title = "NO TITLE";
echo "
<html>
<head>
<title>My Database $title</title>
";
}

setup_page($title); // result: NO TITLE

$title = "";
setup_page($title); // result: NO TITLE

$title = "foo";
setup_page($title); // result: foo

?>

[/code]

You havent got any result div at all in your code

Taking your code, adding a result div - and it's fine in both IE6 and IE7 + FF

[code]

<html>
<head>

<script language="javascript">

function ajaxTest( id )
{
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
}
catch (e){
try{
ajaxRequest = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e){
try{
ajaxRequest = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e){
alert("Your browser broke!");
return false;
}
}
}

ajaxRequest.onreadystatechange = function()
{
if(ajaxRequest.readyState == 4)
{
var ajaxDisplay = document.getElementById(id);
ajaxDisplay.innerHTML = ajaxRequest.responseText;
}
}

var field = document.getElementById('field').value;
var queryString = "?field=" + field;
ajaxRequest.open("GET", "aj_test.php" + queryString, true);
ajaxRequest.send(null);
}
</script>

</head>
<body>

<form action="test.php" method="post" >
<table cellpadding="0" cellspacing="0" class="table_edit" width="800">
<tr>
<td width="40" align="left" valign="middle" >
  <span style="color:#003366; text-decoration:">CNP<span>:  
</td>
<td width="160" align="left" >
<input class="fields2" type="text" id="field" name="cnp" value="" size="15" maxlength="13" />
</td>
<td width="140">
<input class="submit" type="button" name="bigsubmit" value="Search" onclick="ajaxTest('victim');" />
</td>
</tr>
</table>
</form>

<div id="victim"></div>

</body>
</html>

[/code]

..And, you call some <i>strange</i> function in your php file btw

January 28, 2007

My level must be something in the area of "level 2 beginner" - i'm past all those parse errors and i find my way around the manual.

January 28, 2007

As i don't see the point in doing this without using regex, i still found it to be an amusing idea.
None of the above one does the trick, neither will my example - anyhow, here it is:
[code]

<?php

function noregex_email($email){
$main = explode('@', $email);
if(count($main) <> 2){
return false;
}
$domain = explode('.',$main[1]);
if(!in_array(count($domain), array(2,3))){
return false;
}
foreach($domain as $dom){
if(strlen($dom) < 2){
return false;
}
}
$valid = array_merge(range('a','z'), range('0','9'), array('-','_','.'));
foreach(str_split(strtolower($email)) as $char){
if($char == "@") $char = "a";
if(!in_array($char, $valid, true)){
return false;
}
}
return true;
}

?>

[/code]

Sorry for not spotting this sticky - too many stickie makes it tricky (blæh.)

I have an issue with very small fonts inside code areas, thread i made this morning with expl: http://www.phpfreaks.com/forums/index.php/topic,121741.0.html

January 10, 2007

Well, the code is clearly smaller than before and on my laptop (witch i almost without exeption use) and it's simply too small to bother reading now. The fonts melts together in a blur.
I'm running widescreen 14.1" WXGA 1280x768
Must be other than me that notices this and now are having problems reading code contents ?
With the fonts like they are now - sorry, i can't read it on my machine.

January 10, 2007

What happend ? The [ code ] fonts appears very small suddenly.... On my laptop it's now very hard to read.

And you should remove all those session_register(), learn more: http://no2.php.net/manual/en/function.session-register.php

January 8, 2007

Don't think utf-8 will work on those, try
[code]

<?php

$text = str_replace(array("Æ","æ","Ø","ø","Å","å"),array("& # 198;","& # 230;","& # 216;","& # 248;","& # 197;","& # 229;"),$text);

?>

[/code]

*EDIT* some problems getting them visually right displayed in this board... Remove the spaces in the code between "& # foo"

Example with sessions, jumping to another file upon success:
[code]

<?php

session_start();

if(isset($_POST['submit']))
{
$empty_arr = array();

foreach($_POST as $fieldname => $fieldvalue)
{
if(empty($fieldvalue))
{
$empty_arr[] = $fieldname." was left empty";
}
${$fieldname} = $_POST[$fieldname]; // just so that submitted values can be re-displayed in the form if another field value is missing
$_SESSION[$fieldname] = ${$fieldname}; // also store value in a session in case no field values is missing in the end
}

if(!empty($empty_arr))
{
echo "<ul><li>";
echo implode($empty_arr, '</li><li>');
echo "</li><ul>";
}
else
{
header("location: next.php"); // and in next you fetch all current data from $_SESSION['fieldname']

// inside next.php you can put this as a test (uncomment it ofcource):

// <? php
// session_start();
// echo "<pre>";
// print_r($_SESSION);
// echo "</pre>";
// ? >

exit();
}
}

echo <<<_HTML

<form method="post" action="{$_SERVER['PHP_SELF']}">
<p>Name:<br /><input type="text" name="name" value="$name" /></p>
<p>Email:<br /><input type="text" name="email" value="$email" /></p>
<p><input type="submit" name="submit" value="Send" /></p>
</form>

_HTML;

?>

[/code]

January 8, 2007

Here is one example using a function, just include the function on every page you expect to use it
[code]

<?php

function NotDemo(){

$user = htmlspecialchars($_SESSION['user'], ENT_QUOTES);
$check = mysql_query("
SELECT `id`
FROM `login`
WHERE `user` = '$user' AND level = 1
");

if(mysql_num_rows($check) == 1)
{
return true;
}
else
{
Print 'Error: You do not have access.';
include('includes/admin_footer.php');
exit();
}
}

// then use it

if(NotDemo())
{
// ok, made it here so it's not running demo mode
}

?>

[/code]

I don't prefer using echo, include and/or exit within a function check like this - but it works

January 8, 2007

The easiest way is to run the validation on the same page as the form. Usually this is not a problem.

Example:
[code]

<?php

$complete = false;
$empty_arr = array();

foreach($_POST as $fieldname => $fieldvalue)
{
if(empty($fieldvalue))
{
$empty_arr[] = $fieldname." was left empty";
}
${$fieldname} = $_POST[$fieldname];
}

if(!empty($empty_arr))
{
echo "<ul><li>";
echo implode($empty_arr, '</li><li>');
echo "</li><ul>";
}
else
{
// no empty fields, prosess posted values already defined as $fielnames
$complete = true;
}

if($complete == false)
{
echo <<<_HTML

<form method="post" action="{$_SERVER['PHP_SELF']}">
<p>Name:<br /><input type="text" name="name" value="$name" /></p>
<p>Email:<br /><input type="text" name="email" value="$email" /></p>
<p><input type="submit" name="submit" value="Send" /></p>
</form>

_HTML;
}

?>

[/code]

January 8, 2007

You seem to do the mysql_num_rows bit wrong, if num rows is equal to 1 changes are allowed, else no changes can be made.
Another twist is to simply set a session with the level stored and check by that - it will save you a query

Example:
[code]

<?php

// in login, set session as 0 for demo account
$_SESSION['level'] = "0";

// wherever you are about to do some changes, check the session level
if($_SESSION['level'] > "0")
{
// level is above demo, do the desired changes
}
else
{
echo "Demo mode in affect, no changes can be made";
}

?>

[/code]

Your db version would look something like this:
[code]

<?php

$user = htmlspecialchars($_SESSION['user'], ENT_QUOTES);

$check = mysql_query("
SELECT `id`
FROM `login`
WHERE `user` = '$user' AND level = 1
");

if(mysql_num_rows($check) == 1)
{
// do the required task
include('includes/admin_footer.php');
exit();
}
else
{
echo "Demo mode in affect, no changes can be made";
include('includes/admin_footer.php');
exit();
}

?>

[/code]

January 8, 2007

If you want help on this forum you have to bother posting your relevant script here too.
Out of curiosity i tried your link anyhow but it would never load possibly due to a slow server in the other end.

So, post your code!

January 7, 2007

It works if set as 'timestamp' and presumeable as 'datetime'
