for($c=1;$c<=$num;$c++)
{
$row=mysql_fetch_array(mysql_query("SELECT * FROM `$quiztitle` WHERE id=$c"));
if($row['answer']==$_POST['answer'][$c]) // NOT WORKING
{
echo "correct";
echo "<br>";
}
else
{
echo "incorrect";
echo "<br>";
}
}
on the line where it says "NOT WORKING",
the index [$c] does not get the value from the loop.
but when i specify it and change it to $_POST['answer1'], it is working.
what is the correct syntax for this?
Try this.
for($c=1;$c<=$num;$c++)
{
$row=mysql_fetch_array(mysql_query("SELECT * FROM `$quiztitle` WHERE id=$c"));
if($row['answer']==$_POST['answer'.$c]) // NOT WORKING
{
echo "correct";
echo "<br>";
}
else
{
echo "incorrect";
echo "<br>";
}
}
You're treating 'answer' as an array here, looking for an index within.
You want to concatenate the value.
if($row['answer']==$_POST["answer{$c}'])
Based on your note, it looks like you want:
$_POST["answer$c"]
Correct is:
if ($row['answer'] == $_POST['answer' . $c]) {
....
}

So I am trying to echo the value of a key if the key is present in the array. I've go this code at the moment:
<?php
$lingos = array(
"en"=>"en_US",
"en-gb"=>"en_GB",
"nl"=>"nl_NL",
"de"=>"de",
"da"=>"da",
"es"=>"es",
"ca"=>"es_MX",
"fr"=>"fr",
"it"=>"it",
"pt-pt"=>"pt_PT",
"no"=>"no",
"sv"=>"sv",
"fi"=>"fi",
"et"=>"en_GB",
"is"=>"en_GB",
"cs"=>"cs",
"pl"=>"pl",
"lv"=>"en_GB",
"lt"=>"lt",
"hu"=>"hu",
"ro"=>"ro",
"sr"=>"en_GB",
"hr"=>"en_GB",
"bg"=>"bg",
"el"=>"el",
"uk"=>"en_GB",
"ru"=>"ru",
"tr"=>"tr",
"ar"=>"ar",
"zh-hans"=>"zh_CN",
"zh-hant"=>"zh_TW",
"ja"=>"ja",
"ko"=>"ko",
"id"=>"in",
"ms"=>"ms",
"th"=>"th",
"vi"=>"vi",
"pt-br"=>"pt_PT"
);
// foreach($lingos as $lingo => $x_lingo) {
// echo "Key=" . $lingo . ", Value=" . $x_lingo;
// echo "<br>";
// }
$wmpl_langcode = ICL_LANGUAGE_CODE;
echo $wmpl_langcode;
if (array_key_exists($wmpl_langcode, $lingos)) {
echo $lingos[1];
} else {
echo "not found";
}
?>
Thing is, $lingos[1] is not returning anything. What am I doing wrong?
Presumably $wmpl_langcode is something like en as you are checking for it with array_key_exists so use that as the index:
$wmpl_langcode = ICL_LANGUAGE_CODE;
echo $wmpl_langcode;
if (array_key_exists($wmpl_langcode, $lingos)) {
echo $lingos[$wmpl_langcode];
} else {
echo "not found";
}
Or simpler:
echo isset($lingos[$wmpl_langcode]) ? $lingos[$wmpl_langcode] : "not found";
//PHP 7+
echo $lingos[$wmpl_langcode] ?? "not found";
I have two websites, each with it's own domain name. On load I have execute a php file that is used on both sites and has the same functionality.
Here is the code of that file:
<?php
echo '1';
if ($_SESSION["template"]=="template1";)
{
echo '2';
if ($_REQUEST["cmdAction"]=='A')
echo file_get_contents('http://localhost/images/template1/a.php');
else if ($_REQUEST["cmdAction"]=='B')
echo file_get_contents('http://localhost/images/template1/b.php');
else if ($_REQUEST["cmdAction"]=='C')
echo file_get_contents('http://localhost/images/template1/c.php');
}
else if ($_SESSION["template"]=="template2";)
{
echo '3';
if ($_REQUEST["cmdAction"]=='A')
echo file_get_contents('http://localhost/images/template2/a.php');
else if ($_REQUEST["cmdAction"]=='B')
echo file_get_contents('http://localhost/images/template2/b.php');
else if ($_REQUEST["cmdAction"]=='C')
echo file_get_contents('http://localhost/images/template2/c.php');
}
else {
echo 'NO DATA';
}
echo '4';
?>
On each of the two sites I set a session variable but in the above code it doesn't seem to work as I expect it to.
Am i missing something?
remove semicolon from if() and else if() statement, also add brackets when you using nested if else because it makes someone to understand easier and looks better
<?php
echo '1';
if ($_SESSION["template"]=="template1")
{
echo '2';
if ($_REQUEST["cmdAction"]=='A')
{
echo file_get_contents('http://localhost/images/template1/a.php');
}
else if ($_REQUEST["cmdAction"]=='B')
{
echo file_get_contents('http://localhost/images/template1/b.php');
}
else if { ($_REQUEST["cmdAction"]=='C')
{
echo file_get_contents('http://localhost/images/template1/c.php');
}
}
else if ($_SESSION["template"]=="template2")
{
echo '3';
if ($_REQUEST["cmdAction"]=='A')
{
echo file_get_contents('http://localhost/images/template2/a.php');
}
else if ($_REQUEST["cmdAction"]=='B')
{
echo file_get_contents('http://localhost/images/template2/b.php');
}
else if ($_REQUEST["cmdAction"]=='C')
{
echo file_get_contents('http://localhost/images/template2/c.php');
}
}
else {
echo 'NO DATA';
}
echo '4';
?>
After reviewing your code I edited my answer. The below code will do exactly the same as your code but requires alot less code.
<?php
if (isset($_SESSION['template']) && isset($_REQUEST['cmdAction'])) {
echo file_get_contents('http://localhost/images/'.$_SESSION['template'].'/'.strtolower($_REQUEST['cmdAction']).'.php');
} else {
echo 'NO DATA';
}
?>
I have a simple PHP code, as below.
When I try the URL localhost/df.php?result1=bharat, I get the result Bharat, exactly as I want it. But when I try the URL localhost/df.php?result2=bharat, I get an error, meaning my result2 variable was not read like my result1 variable did.
Could you please correct my code so that it works?
<?php
if(isset($_GET['Result1']))
{
$file = $_GET['Result1'];
}
else
{
echo "Error"; exit;
}
echo "$result1";
?>
elseif(isset($_GET['Result2']))
{
$file = $_GET['Result2'];
}
else
{
echo "Error"; exit;
}
echo "$result2";
?>
You have way too many errors in your code. The following is the solution to your problem:
<?php
if(isset($_GET['result1']))
{
$result1 = $_GET['result1'];
echo $result1;
}
elseif(isset($_GET['result2']))
{
$result2 = $_GET['result2'];
echo $result2;
}
else
{
echo "Error";
exit();
}
?>
For the future, I would recommend you to learn PHP and be familiar with the basic syntax, at least, before posting questions about it here.
this is by Far the weirdest thing i have ever seen and i am completely confused. please someone help me with this.
$variable=array();
$count=0;
// now im am going to loop through a resource that i made
while(!feof($job))
{
$data=fgets($job);
// i am search for different things below. search for name, date, employer
// i am using regex to search btw
// presume object in class works fine, and they do.
if(search for eg name in $data, storing in $variable[$count].first($match))
// the problem is at this point i will have access to
// $variable[$count].getFirst(returns value set by first) which was set above;
if(search for eg Employer in $data, storing in variable[$count].next($match))
// i will have access here as well
// $variable[$count].getFirst(returns value set by first) which was set above
if(search for 3rd search in $data, storing in variable[$count].name($match))
// down here after the second if i am not able to see any of my variables set more than 2 if statements ago????
// $variable[$count].getFirst(does not returns the value set by first()) which was set above
if(search for 4th search in $data, storing in variable[$count].foo($match))
// check if everything is set then count++;
}
Now each one of these methods are completely dependent from the next but after 2 if statements. I am just not able to access $variable[count]->getfirst()
the answer is null;

this is the actual code

everything works except the $profile[number] doesn't store anything in it at all after the 3 rd if statement when the variable is stored.
If
{
//Profile[number] info stored
}
if
{
//Profile[number] info available
}
if
{
//profile[number] info available
}
if
{
//profile[number] info is gone
}
variable[$count].next($match)
the .next() moves the internal pointer to the next element in the array.
I have a variable that is posted through a html form:
$_POST['ref']
And a variable that is pulled from a table in a database:
$row['ref']
i have a basic comparison script to check if they are both the same:
$ref = $_POST['ref'];
$result = mysql_query("SELECT * FROM logbook.job");
if (!$result) {
die("Query to show fields from table failed");
}
$row = mysql_fetch_array($result);
$refdb = $row['ref'];
$refform = $_POST['ref'];
echo $_POST['ref'] ."<br>". $row['ref'] . "<br><br>";
if ($refdb == $refform) {
echo "Yes they are<br><br>";
}
else {
echo "No they are not<br><br>";
}
if (is_string($_POST['ref']))
{
echo "Yes";
} else {
echo "No";
}
echo "<br>";
if (is_string($row['ref']))
{
echo "Yes";
} else {
echo "No";
}
Which outputs:
G2mtxW
G2mtxW
No they are not
Yes
Yes
I echo them both out. Than i ask if they are the same. Then i check whether each is a string.
How come they are not the same? How can i get them to match
Any help would be appreciated
Try using the binary-safe comparison for String:
result = strcmp($str1, $str2);
If the result is 0, then both are the same. Otherwise, they aren't.
One of your strings (probably the one from the DB) might be null-terminated. I've tested the following
$foo = "abc\0";
$bar = "abc";
echo "$foo\n$bar\n";
if($foo == $bar)
echo "Equal.";
else
echo "Not equal."
Output is
abc
abc
Not equal.
Try var_dump-ing both values, check their lengths and inspect them using view-source. They are different in someway.
echo $status_message;
echo "Accepted";
if(strcmp($status_message,"Accepted")==0)
{
echo "equal";
}
else
{
echo "not equal";
}
?>
$row['status'] is a field from table
