I'm trying to solve this for some time. I have PHP function that is called on link click. When I click on link it's directing me to this function but it's not giving any results.
Here is how I call function.
foreach ($bandsN as $aa) {
$str = explode(',', $aa);
$next = $str[1];
?>
<?php echo $str[0]?> </div> <?php
if (isset($_GET['other'])) {other($next);}
}
In this function it's called mysql stored procedure with parameter of php function.
function other($var)
{
echo $var;
if (!$mysqli->multi_query("CALL p($var)")) {
echo "CALL failed: (" . $mysqli->errno . ") " . $mysqli->error;
}
do{
if($resul = $mysqli->store_result()){
$bands = array();
while($ro = $resul->fetch_row())
{
$bands[] = implode(',', $ro);
}
foreach ($bands as $aa) { ?>
<p > <?php echo $aa?> </p> </div><?php
}
$resul->free();
unset($bands);
}}
while($mysqli->more_results() && $mysqli->next_result());
}
I don't know which is the problem. This code inside function is working because I already have it in other part of app.
If somebody can see what is wrong I would be very grateful.

I am making a tool to convert steam profile urls to the different steam ids, whatever.
I have the different functions, triggered when submitting the URL of the profile with a form.
One of the function are, that it gets the avatar of the regarding steam profile.
Actually it gets the link of the image. What I can do is, echo an img element with the link, this wont give me any flexibility since I wont be really able to style etc that afterwards.
Now, the function of getting the avatar, is in the function of the submit form.
I tried just inserting the image URL into an img element.
<img src"<?php echo $avatar ?>">
Well, then I get a error message, saying "$avatar" is undefined, even though I defined it in my main php tags. I think that is due to the fact that it is done inside the form function, could be wrong though.
My main question now is, what could be a different approach to this? I need that in the form function because it should only be called then.
Maybe I just have to use the inconvenient way of echoing an img element every time.
Here is the actual code.
<form method="post">
<input type="text" name="profile_url">
<input type="submit" value="click" name="submit">
</form>
<div id="avatar-div" style="height:100px; width:100px;">
<img src="<?php echo $avatar; ?>">
</div>
the main php part
if(isset($_POST['submit']))
{
display();
}
function display() {
require_once 'steamid.class.php';
$input = $_POST["profile_url"];
$api_key = "xxxxxxxxxxxxxxx";
$id = new SteamID($input,$api_key);
if(substr_count($input, ' ') === strlen($input)) {
echo "Enter URL";
} else {
if ($id->resolveVanity()) {
$avatar = $id->toAvatar();
$communityid = $id->toCommunityID();
echo $communityid . ", " . " ";
$steamid = $id->toSteamID();
echo $steamid . ", " . " ";
$userid = '[U:1:'.$id->toUserID().']';
echo $userid . ", " . " ";
} else {
echo "Profile wasnt found!";
}
}
}
I'm refactoring my answer based on the conversation we had. Here is the recommended PHP code.
function urlCheck() {
$input = $_POST["profile_url"];
if(empty($input)) {
echo "Enter URL";
return false;
} else {
return true;
}
}
function display() {
require_once 'steamid.class.php';
$api_key = "xxxxxxxxxxxxxxx";
$id = new SteamID($input,$api_key);
if (urlCheck()) {
if ($id->resolveVanity()) {
$communityid = $id->toCommunityID();
echo $communityid . ", " . " ";
$steamid = $id->toSteamID();
echo $steamid . ", " . " ";
$userid = '[U:1:'.$id->toUserID().']';
echo $userid . ", " . " ";
return $id->toAvatar();
} else {
echo "Profile wasn't found!";
}
}
}
You haven't mentioned where you're running display(), or where you're expecting the output (echo) to display. I can only assume you want it at the top of the page. Let me explain how to use this.
<head>
$avatar = display();
</head>
<body>
<div id="avatar-div" style="height:100px; width:100px;">
<img src="<?= $avatar ?>">
</div>
</body>
Basically the way this works, is that wherever you run display(), is where the echoes will output (in this case, before the body). Wherever you echo $avatar is where the id will be displayed. I hope this works for you.
Take a look at PHP's Variable Scope
Any variable used inside a function is by default limited to the local function scope.
To fix this problem, use the global keyword. This way you will explicitly set $avatar; as a global variable so it can be used outside of your display() function.
Here is how it would work for your example:
function display() {
global $avatar;
// Rest of your display() function
// Set $avatar somewhere in here
}
display(); // Actually call display so $avatar is set
<div id="avatar-div" style="height:100px; width:100px;">
<img src="<?=$avatar;?>">
</div>
I'm a beginner in php. I'm trying get a variable number from sql ,
I have this part of code:
function renderNotification()
{
if ($user_id = $this->getDi()->auth->getUserId()) {
$cnt = $this->getDi()->db->selectCell("SELECT COUNT(ticket_id) FROM ?_helpdesk_ticket WHERE status IN (?a) AND user_id=?",
array(HelpdeskTicket::STATUS_AWAITING_USER_RESPONSE), $user_id);
if ($cnt)
return '<div class="am-info">' . ___('You have %s%d ticket(s)%s that require your attention',
sprintf('', REL_ROOT_URL . '/helpdesk/index/p/index/index?&_user_filter_s[]=awaiting_user_response'), $cnt, '') .
'</div>';
}
}
i want get number of ticket only in other place in my program
This is my try:
<?php echo "%s%d" ; ?>
or
<?php echo $cnt ; ?>
but not work
i'm using Zend , sf , pear , all what i need output %s%d ticket(s)%s from above code in other place or call it
i have found correct way it's below
<?php
$cnt = $di->db->selectCell("SELECT COUNT(ticket_id)
FROM ?_helpdesk_ticket
WHERE status IN (?a)
AND user_id=?",
array(HelpdeskTicket::STATUS_AWAITING_USER_RESPONSE),
$di->user->pk());
echo $cnt;
?>
I have a search field in the page. But if there is no matching results, it is throwing an error "Fatal error: Call to a member function show() on a non-object". I have attached the screenshot.
<?php
if ( isset($_REQUEST['usersearch']) && $_REQUEST['usersearch'] )
printf( '<span class="subtitle">' . __('Search results for “%s”') .
'</span>', esc_html( $_REQUEST['usersearch'] ) );
?>
But the error line is (228th line):-
<div class='tablenav-pages'>
<?php echo $p->show(); // Echo out the list of paging. ?>
</div>
I need to remove the error on search result. It should simply show "No items found".
function pager($items)
{
global $limit;
global $p;
global $searchTerm;
global $pageLimit;
if($items > 0) {
$p = new pagination;
$p->items($items);
$p->limit($pageLimit); // Limit entries per page
$p->target("admin.php?page=User Control&usersearch=".$_REQUEST['usersearch']."&page-limit=".$_REQUEST['page-limit']);
$p->currentPage($_GET[$p->paging]); // Gets and validates the current page
$p->calculate(); // Calculates what to show
$p->parameterName('paging');
$p->adjacents(1); //No. of page away from the current page
if(!isset($_GET['paging'])) {
$p->page = 1;
} else {
$p->page = $_GET['paging'];
}
//Query for limit paging
$limit = "LIMIT " . ($p->page - 1) * $p->limit . ", " . $p->limit;
} else {
echo "No Record Found";
}
}
Your getting the error because your attempting to show a object that is undefined...use a statement to check...this is the premise.
<div class='tablenav-pages'>
<? if(is_object($p)){echo $p->show();} ?>
</div>
<?php
if (isset($p) && is_object($p)){
$p->show();
}
?>
Here's my piece of code(full body code):
<body>
<script type='text/javascript'>
function AddEvent(Syear, Smonth, Sday, Eyear, Emonth, Eday, hallNumber){
...
}
</script>
<?php
function GetMonthByCoding($first , $second , $third) {
...
}
function GetDateByCoding($coding){
...
}
function GetDateFromLine($line){
...
}
$userid = '...';
$magicCookie = 'cookie';
$feedURL = "...";
$sxml = simplexml_load_file($feedURL);
foreach ($sxml->entry as $entry) {
$title = stripslashes($entry->title);
if ($title == "HALL") {
$summary = stripslashes($entry->summary);
$date = GetDateFromLine($summary);
echo ("<script type='text/javascript' language='JavaScript'> AddEvent(" . $date['start']['year'] . ", " . $date['start']['month'] . ", " . $date['start']['day'] . ", " . $date['end']['year'] . ", " . $date['end']['month'] . ", " . $date['end']['day'] . "); </script>");
}
}
?>
</body>
AddEvent() is JavaScript function defined earlier.
What I get in my browser is:
entry as $entry) { $title = stripslashes($entry->title); if ($title == "HALL") { $summary = stripslashes($entry->summary); $date = GetDateFromLine($summary); echo (""); } } ?>
Looks like it was an echo but as you can see there is no echo right in the middle of foreach.
Can anyone say what I am doing wrong?
PHP is not installed, or it is not enabled, or the file is not a .php file or the server has not been told to recognise it as a file to parse.
Try View Source and you should see all your PHP code. The only reason part of it shows up is because everything from <?php to the first > is considered by the browser to be an invalid tag.
I found the problem, it was in the name of variable sxml. I renamed it and the problem escaped.
I am having trouble with modifying a php application to have pagination. My error seems to be with my logic, and I am not clear exactly what I am doing incorrectly. I have had before, but am not currently getting errors that mysql_num_rows() not valid result resource
and that invalid arguments were supplied to foreach. I think there is a problem in my logic which is stopping the results from mysql from being returned.
All my "test" echos are output except testing while loop. A page is generated with the name of the query and the word auctions, and first and previous links, but not the next and last links. I would be grateful if a more efficient way of generating links for the rows in my table could be pointed out, instead of making a link per cell. Is it possible to have a continuous link for several items?

edit: I have printed out the mysql error of which there was none. However 8 "test whiles" are printed out, from a database with over 100 records. The foreach loop is never entereded, and I am unsure why.
The problem (or at least one of them) is in the code that reads:
$rows = getRowsByProductSearch($query, $table, $max);
$numRows = mysql_num_rows($rows);
The $numRows variable is not a MySQL resultset, it is just a normal array returned by getRowsByProductSearch.
Change the code to read:
$rows = getRowsByProductSearch($query, $table, $max);
$numRows = count($rows);
Then it should at least find some results for you.
Good luck, James
Hi there,
The next problem is with the line that reads:
$last = ceil($rows/$page_rows);
It should be changed to read:
$last = ceil($numRows / $page_rows);
Would recommend adding the following lines to the start of you script at least while debugging:
ini_set('error_reporting', E_ALL | E_STRICT);
ini_set('display_errors', 'On');
As that would have thrown up a fatal error and saved you a whole lot of time.
if (!(isset($pg))) {
$pg = 1;
}
How is $pg going to get set? You don't appear to be reading it from $_GET. If you're relying on register_globals: don't do that! Try to read it from $_GET and parse it to a positive integer, falling back to '1' if that fails.
<a href='{$_SERVER['PHP_SELF']}?pg=$next'>Next -></a>
You appear to be losing the other parameters your page needs, 'query' and 'cmd'.
In general I'm finding it very difficult to read your code, especially the indentation-free use of echo(). Also you have untold HTML/script-injection vulnerabilities every time you "...$template..." or .concatenate a string into HTML without htmlspecialchars()ing it.
PHP is a templating language: use it, don't fight it! For example:
<?php
// Define this to allow us to output HTML-escaped strings painlessly
//
function h($s) {
echo(htmlspecialchars($s), ENT_QUOTES);
}
// Get path to self with parameters other than page number
//
$myurl= $_SERVER['PHP_SELF'].'?cmd='.urlencode($cmd).'&query='.urlencode($query);
?>
<div id="tableheader" class="tableheader">
<h1><?php h($query) ?> Sales</h1>
</div>
<div id="tablecontent" class="tablecontent">
<table border="0" width="100%"> <!-- width, border, cell width maybe better done in CSS -->
<tr>
<td width="15%">Seller ID</td>
<td width="10%">Start Date</td>
<td width="75%">Description</td>
</tr>
<?php foreach ($rows as $row) { ?>
<tr id="row-<?php h($row['Product_NO']) ?>" onclick="updateByPk('Layer2', this.id.split('-')[1]);">
<td><?php h($row['USERNAME']); ?></td>
<td><?php h($row['shortDate']); ?></td>
<td><?php h($row['Product_NAME']); ?></td>
</tr>
<?php } ?>
</table>
</div>
<div class="pagercontrols">
<?php if ($pg>1) ?>
<<- First
<?php } ?>
<?php if ($pg>2) ?>
<-- Previous
<?php } ?>
<?php if ($pg<$last-1) ?>
Next -->
<?php } ?>
<?php if ($pg<$last) ?>
Last ->>
<?php } ?>
</div>
Is it possible to have a continuous link for several items?
Across cells, no. But you're not really using a link anyway - those '#' anchors don't go anywhere. The example above puts the onclick on the table row instead. What exactly is more appropriate for accessibility depends on what exactly your application is trying to do.
(Above also assumes that the PK is actually numeric, as other characters may not be valid to put in an 'id'. You might also want to consider remove the inline "onclick" and moving the code to a script below - see "unobtrusive scripting".)
This is wrong:
if($cmd=="GetRecordSet")
echo "test in loop\n"; {
It should be:
if($cmd=="GetRecordSet") {
echo "test in loop\n";
In your getRowsByProductSearch function, you return the result of mysql_error if it occurs. In order to debug the code, maybe you can print it instead, so you can easily see what the problem is.
