PHP - Function Issue
Hi,
I have just started learning php and mysql and have been doing a few exercises. I made a function to get all the information out of a table in a mysql database based on the id of a selected table item. I'm having a bizarre issue when trying to use the function within an if statement. It works fine when I use it and assign to a variable in my page. Like so: <?php $table = get_table_by_id ($_GET ["subj"]); echo $table ["menu_name"]; ?> This gives me the menu name out of the table. However when the same function is used within an if statement like so: if (isset($_GET ["subj"])) { $sel_table = get_table_by_id ($_GET ["subj"]); } else { $sel_table = NULL; } I get the following error: Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in.... Which translates to: No database selected Here is the code used for the function: function get_table_by_id ($name) { $query = "SELECT * " ; $query .= "FROM pages "; $query .= "WHERE id=" . $name . " "; $query .= "LIMIT 1"; $result_set = mysql_query ($query); if (!$result_set) { die ("query failed " . mysql_error()); } $array = mysql_fetch_array($result_set); return $array; Why is this happening? Similar TutorialsHi Guys I have created a function, well i think i have function datedropdown_funct() { switch ($date_filter) { case "Today": $retval = '<option value="">Select</option><option value="Today" SELECTED>Today</option><option value="Last 48hrs">Last 48hrs</option><option value="Last week">Last Week</option><option value="last month">Last Month</option>'; break; case "Last 48hrs": $day = date("d")-1; $retval = '<option value="">Select</option><option value="Today">Today</option><option value="Last 48hrs" SELECTED>Last 48hrs</option><option value="Last week">Last Week</option><option value="last month">Last Month</option>'; break; case "Last week": $day = date("d")-7; $retval = '<option value="">Select</option><option value="Today">Today</option><option value="Last 48hrs">Last 48hrs</option><option value="Last week" SELECTED>Last Week</option><option value="last month">Last Month</option>'; break; case "last month": $month = date("m")-1; $retval = '<option value="">Select</option><option value="Today">Today</option><option value="Last 48hrs">Last 48hrs</option><option value="Last week">Last Week</option><option value="last month" SELECTED>Last Month</option>'; break; case "last 3 months": $month = date("m")-3; $retval = '<option value="">Select</option><option value="Today">Today</option><option value="Last 48hrs">Last 48hrs</option><option value="Last week">Last Week</option><option value="last month">Last Month</option><option value="last 3 months" SELECTED>Last 3 Month</option>'; break; default: // Default is the last 48hrs $day = date("d")-1; } return $retval; } it gets called like so $date_filter_options= datedropdown_funct(); The variable $date_filter_options should take on the $retval value, but it doesnt appear to be calling the function Any ideas or correction where i have screwed up ? regards Hi php freaks I have been going through someone elses code and have seen this below. What does the & at the start of the function do? Code: [Select] function &foo(){} Thanks Hi, When i am getting the part of the text using the function substr, am getting this kind of problem , (text in the end not printing properly) how to solve this. تسر مؤسسة مهارات التقنية ومؤسسة اشبكة الثنائية ان تطلع جميع عملاءها بإصدار نظام تاتش لإدارة الموقع الالكترونية من يوم السبت ا� This is the code am using $sub_string_content = substr($temp['News_Content'],0,300); Thanks, Hi im just wondering whats up with this - i am just doing a plain php mail function

I'm trying to call UploadObj.uploadFile(); on a click event.
Removing the "var" to make the scope global works sort of but also throws errors.
Not sure what to do. Help appreciated.

I'm currently getting the following message; Warning: mysql_fetch_array() expects parameter 1 to be resource, null given in C:\xampp\htdocs\duff3\test3.php on line 25 Can anyone figure out and explain why this isn't working for me, I believe I am calling the function correctly and then putting the result into a while loop.

function parentFunction($variable) { function childFunction() { echo 'Argument of the parent function is '.$GLOBALS['variable']; } childFunction(); } parentFunction(5); What I want to know is - Is there a way to access a variable from the parent function without passing arguments to the child function? (Something like how classes have parent::?). I don't want to use $GLOBALS because it might cause some variable collision, and I didn't want to pass arguments because incase I decide to change the arguments in the parent function I'd have to do it in the child function aswell. From my searching around in the Internet it seems like this is not possible, but if theres a slight chance that there might be something out there, i'm willing to give it a shot . Thanks in advance Question 1) Is the only and proper way to call a parent function "parent::function()"? Are there other/better ways from within a child function? Question 2) What are the deciding factors for when to make a function or attribute static? How do you make that decision? Assuming 5.3... Thanks. I have this function completely written in my class file that I am working on. The point to this function is to be able to check the login of a user or administrator for either of the control panels associated with my site. It will check the session intime as well as the page / module referenced. Once it passes all those checks, it will check and ensure the emailaddress/password stored in the current session still holds true and the account is still active... if the account is still active it will update the lastActivity as well as update all of the session variables with what is currently in the database. What I am looking for is basically a look at the function, see if it looks good.. If there is any part to it that could create security holes for the site just off the login function itself... Usage: $q->validUser($_SESSION['user'], $_mod); <?php function validUser($sess, $p) { if ($sess['inTime'] == '' && $p != 'login' && $p != 'logout') { session_destroy(); $login = '0'; $_int = ''; return $login; } else if ($sess['inTime'] < time()-3600 && $p != 'login') { $sess['inTime'] = ''; session_destroy(); $this->check_login($sess, $p); } else { $this->user = $sess['emailAddress']; $this->pass = $sess['password']; $login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' AND status = '1' LIMIT '1'"); if ($login = $this->sql_numrows($login) < 1) { $sess['inTime'] == ''; session_destroy(); $login = '0'; } else { // logged in, lets update the database for last_activity AND the session. $this->sql_query("UDATE users SET lastActivity = '".now()."' WHERE emailAddress = '".$this->user."'"); $login = $this->sql_query("SELECT * FROM users WHERE emailAddress = '".$this->user."' AND password = '".$this->pass."' AND status = '1' LIMIT '1'"); $login = mysql_fetch_assoc($login); foreach ($login as $key => $value) { $sess[$key] = $value; } $sess['inTime'] = time(); $login = '1'; } return $login; } } ?> That is the main function, sql_query and sql_numrows is: <?php function sql_query($query = "", $transaction = FALSE) { unset($this->query_result); if ($query != "") { $this->num_queries++; if ($transation == BEGIN_TRANSACTION && !$this->in_transation) { $result = mysql_query("BEGIN", $this->db_connect_id); if (!$result) { return false; } $this->in_transaction = TRUE; } $this->query_result = mysql_query($query, $this->db_connect_id); } else { if ($transaction == END_TRANSACTION && $this->in_transaction ) { $result = mysql_query("COMMIT", $this->db_connect_id); } } if ($this->query_result) { unset($this->row[$this->query_result]); unset($this->rowset[$this->query_result]); if ($transaction == END_TRANSACTION && $this->in_transaction ) { $this->in_transaction = FALSE; if (!mysql_query("COMMIT", $this->db_connect_id)) { mysql_query("ROLLBACK", $this->db_connect_id); return false; } } return $this->query_result; } else { if ($this->in_transaction ) { mysql_query("ROLLBACK", $this->db_connect_id); $this->in_transaction = FALSE; } return false; } } function sql_numrows($query_id = 0) { if(!$query_id) { $query_id = $this->query_result; } return ($query_id) ? mysql_num_rows($query_id) : false; } ?> Any insight that can help to benefit these functions would be appreciated. I need to call usort from a class function, and I'm puzzled about how to define the comparison function. I've tried to define the comparison function in the same class, but I can't get usort to call it. I found one hint that it will work if I make the comparison function static, but I tried that, and it didn't work for me. If I define the comparison function outside the class, it won't have access to object properties that it needs to operate. The only solution I can think of is to define the comparison function outside the class and put the object properties it needs in globals. Is there a cleaner way to do this? Hi, I have this code below which groups all the SubHeading together and then queries the same table to find RiskConsequence which are grouped that match SubHeading then to query this table one more last time with all the Risk Mitigation that matches the grouped RiskConsequence. Problem I get is it does the SubHeading, the RiskConsequences it only does one of them not all of them before it moves onto the RiskMitigation. I know I have a php coding issue just cant see the wood from the tree's as the queries work. Code: [Select] <?php include ("include.php"); $query = "SELECT * FROM tblriskassessmentdatabank GROUP BY SubHeading"; $results = mysql_query($query) or die("Error: " . mysql_error()); while($row1 = mysql_fetch_array($results)){ echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row1[SubHeading]);echo"'))";echo'">';echo($row1[SubHeading]);echo'</a><br /><br />'; echo'<div id="';echo($row1[SubHeading]); echo'" class="HideText">'; $risksub = $row1[SubHeading]; $query1 = "SELECT * FROM tblriskassessmentdatabank GROUP By RiskConsequence"; $results1 = mysql_query($query1) or die("Error: " . mysql_error()); while($row2 = mysql_fetch_array($results1)){ echo'<a href="#" onClick="return(changeDisplay(';echo"'";echo($row2[RiskConsequence]);echo"'))";echo'">';echo($row2[RiskConsequence]);echo'</a><br />'; echo'<div id="';echo($row2[RiskConsequence]); echo'" class="HideText">'; $risksub1 = $row2[RiskConsequence]; $query1 = "SELECT * FROM tblriskassessmentdatabank WHERE RiskConsequence = '$risksub1'"; $results1 = mysql_query($query1) or die("Error: " . mysql_error()); while($row3 = mysql_fetch_array($results1)){ echo'<input name="checkbox[]" type="checkbox" id="checkbox[]" value="';echo($row3[IssueNumber]);echo'" /> <label for="checkbox[]"></label>';echo($row3[RiskMitigation]);echo'<br /><br />'; } echo'</div>'; } echo'</div>'; } ?> Folks, I remember once having a php or html5 issue where the first option had to be blank in the drop down. Otherwise, it wasn't working. What wasn't working ? How wasn't working ? I can't remember. either php had difficulty reading user input or the drop down was not showing any options. And so, I had to add a blank value. So, something like this wasn't working ...
<label for="tos_agreement">Agree to TOS or not ?</label> <select name="tos_agreement" id="tos_agreement"> <option value="yes">Yes</option> <option value="no">No</option> </select>
And, I think I added a blank value, at somebody's advice, to get it to work. I think it was something like this, if I remember correctly:
<label for="tos_agreement">Agree to TOS or not ?</label> <select name="tos_agreement" id="tos_agreement"> <option value=" ">Select here</option> <option value="yes">Yes</option> <option value="no">No</option> </select>
Or, maybe it was something like this:
<label for="tos_agreement">Agree to TOS or not ?</label> <select name="tos_agreement" id="tos_agreement"> <option value=" "></option> <option value="yes">Yes</option> <option value="no">No</option> </select>
I can't remember. All I remember slightly that there was a blank value. I been going through my php files to find that particular file to jog my memory but I failed to find it. Can you folks explain to me if a blank value is required or not ? What is the benefit/disaster of adding it and how should the blank value be added ? Show me an example.
Was this a php or html 5 issue ? Can anybody fugure ?
Thank You When I put this chunk of code into it's own function: function fetch_all ($dbc, $query) { include ('knuffix_list_func.php'); pagination_start ($dbc, $query); $offset = $pag_array[0]; $rows_per_page = $pag_array[1]; $query = $query . " LIMIT $offset, $rows_per_page"; echo "test query: " . $query; knuffix_list ($query, $dbc); pagination_end ($pag_array); } And when I echo out the query as you can see in the example, then I notice that the variables $offset and $rows_per_page never get appended. I set the variable $pag_array to a global inside the function pagination_start(). It usually works when I DON'T wrap a function around this chunk of code, but if I do wrap a function around everything then the global suddenly won't work anymore. Btw, this also won't work if I wrap a function around the function DECLARATIONS. Any ideas, how I could make it work? I want to define a function instead of repeating query in all my php pages. I call a function by passing an $id value and from that function i have to get all the info related to that id, like name, description and uom.
I am trying to do this, but i dont know how to get these values seperately.
here is my function
function items($item_id)
{
$details = array();
$result = mysql_query("select item_id, name, uom, description from items where item_id=".$item_id."") or die (mysql_error());
while($row = mysql_fetch_array($result))
{
$details[] = array((stripslashes($row['name'])), (stripslashes($row['uom'])), (stripslashes($row['description'])));
}
return $details;
}
and i call my function like this
$info = items($id);Can somebody guide me in this im using a function which connects to a db called 'comments' and then inside that function i again called another function that will connect to the db 'main' to get avatars.... but as i put Code: [Select] mysql_select_db("main") or die(mysql_error()); on the new function, the original function stops to fetch rows. i tried to remove "mysql_select_db("main") or die(mysql_error());" and used the new function to return some text only and it worked, so i guess the connection to the db was the problem... i tried doing Code: [Select] mysql_query("SELECT * FROM main.avatar INNER JOIN main.list ON main.avatar.title=main.list.id WHERE main.avatar.page_id='$id'"); but it also didnt work Hi all, I want to call a javascript function from a php function like this: public function Buscar() { $HoraInicio = $_POST['edtHoraInicio']; $HoraFin = $_POST['edtHoraFin']; $FechaInicio = $_POST['edtFec1']; $FechaFin = $_POST['edtFec2']; $FechaMax = $FechaFin." ".$HoraFin.":00"; $FechaMin = $FechaInicio." ".$HoraInicio.":00"; $_GET["FechaMax"] = $FechaMax; $_GET["FechaMin"] = $FechaMin; echo $FechaMin; echo "<script language=javascript>alert('Hi.')</script>"; } but the function Buscar never show the alert but shows the $FechaMin I hopu u guys can help me out with this probem Thanks, Siddhartha I've followed the PHP Freaks pagination tutorial which you can find here. And I also got it to work, the only problem is that the script won't work when I use the query outside of the function. Here's the function: <?php function knuffix_list ($query, $dbc) { // find out how many rows are in the table: $query_row = "SELECT COUNT(*) FROM con"; $query_run = mysqli_query ($dbc, $query_row); $row = mysqli_fetch_row($query_run); $num_rows = $row[0]; // number of rows to show per page $rows_per_page = 5; // find total pages -> ceil for rounding up $total_pages = ceil($num_rows / $rows_per_page); // get the current page or set a default if (isset($_GET['current_page']) && is_numeric($_GET['current_page'])) { // make it an INT if it isn't $current_page = (int) $_GET['current_page']; } else { // default page number $current_page = 1; } // if current page is greater than total pages then set current page to last page if ($current_page > $total_pages) { $current_page = $total_pages; } // if current page is less than first page then set current page to first page if ($current_page < 1) { $current_page = 1; } // the offset of the list, based on current page $offset = (($current_page - 1) * $rows_per_page); echo "test " . $query; // SCRIPT ONLY WORKS IF I INSERT QUERY HERE $query = "SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT $offset, $rows_per_page"; $data = mysqli_query ($dbc, $query) or die (mysqli_error ($dbc)); // Loop through the array of data while ($row = mysqli_fetch_array ($data)) { global $array; // Variables for the table $con_id = $row['con_id']; $likes_count = $row['likes']; $dislikes_count = $row['dislikes']; $dbuser_name = $row['nickname']; $dbuser_avatar = $row['avatar']; $user_id = $row['user_id']; // The TABLE echo "<table padding='0' margin='0' class='knuffixTable'>"; echo "<tr><td width='65px' height='64px' class='avatar_bg' rowspan='2' colpan='2'><img src='avatar/$dbuser_avatar' alt='avatar' /></td>"; echo "<td class='knuffix_username'><strong><a href='profile.php?user=$dbuser_name' title='Profile of $dbuser_name'>" . $dbuser_name .

I put the test echo above the query to see how the query looks like when I induce the query from the outside through the function parenthesis into the function, and this is what I get printed out: test SELECT * FROM con, user WHERE con.user_id = user.user_id ORDER BY contributed_date DESC LIMIT , Obviously the $offset and the $rows_per_page variables are not set, when I induce the query from the outside into the function. So in that sense my question is: How can I induce the query from the outside into the function SO THAT the $offset and the $rows_per_page variables are set as well and NOT empty? p.s. I need the query outside of the function because I'm using a sort by category functionality. Hi I have a table class and functions I want to call in another function but can't get it working. Some help will be very welcome. It seesm that the new table class is not working in this function if I pass the values to it, I have tested the class, it does get the post values I post to it so $_POST['id'] are being received as well as all the other $_POST's but the table class and find function is not working, it works fine if I don't put it in a function.. function edit() { if (isset($error)){ $error.="Please fix the error(s) above";} else { if ($_POST['id'] <> "") { $update =& new table($db, 'publisher'); $update->find($_POST['id']); $update->name = $_POST['name']; $update->url = $_POST['url']; $update->contact = $_POST['contact']; $update->address = $_POST['address']; $update->phone = $_POST['phone']; $update->email = $_POST['email']; $update->save(); $error = "The Publisher has been edited"; } } } can you do that with php? Code: [Select] Database2() { function test($id) { $newdb = new Database2(); $newdb->test($id); } }
window.setInterval(function(){
s="<?= $lastid ?>";
$.post('../action/updatestream.php',{statusid:s.val()},function(e){
alert(e)
});
}, 10000);
Why isn't it working?Thanks, |
