I have a PHP script and MSSQL tables, I got the answer key in a variable stored in $right_answer and user selected answers in $user_answer_select THe format is something like this
5+10?
A) 10
B) 15
C) 20
D) 25
E) 50
Answer key: B
what I want to do is put a check mark next to B if its correct and a X if it is wrong, how would I make the if else statements here?
This is the code I currently have
if(($user_answer_select == $right_answer) && $user_answer_select == 'a') $a_sel = "<img src=\"tick_icon.gif\">";
else if(($user_answer_select == $right_answer) && $user_answer_select == 'b') $b_sel = "<img src=\"tick_icon.gif\">";
else if(($user_answer_select == $right_answer) && $user_answer_select == 'c') $c_sel = "<img src=\"tick_icon.gif\">";
else if(($user_answer_select == $right_answer) && $user_answer_select == 'd') $d_sel = "<img src=\"tick_icon.gif\">";
else if(($user_answer_select == $right_answer) && $user_answer_select == 'e') $e_sel = "<img src=\"tick_icon.gif\">";
This is wrong because some of the questions that don't have answers for are highlighted as true. What's the way to do this?
$answers = array ( "A"=>10, "B"=>15, "C"=>20, "D"=>25, "E"=>50 );
$right_answer = "B";
$user_selected_answer = "A";
echo "5+10?<br/>";
foreach ($answers as $key => $value) {
echo $key.") ".$value;
if ($value === $user_selected_answer) {
if ($value === $right_answer){ echo "check!"; }
else { echo "X"; }
}
echo "<br/>";
}
echo "Answer key: $right_answer";
if ( $user_answer_select == $right_answer ) {
$correct = true;
} else {
$correct = false;
}
Then in the correct answer on the form:
<?php echo $correct == true ? 'x' : ''; ?>

$var1="exit";
$var2="run";
$var3="go";
if($var1 != '' && $var2 != '' && $var3 != '' ){
//first condtion
if($var1 == 'clear'){
echo 'clear';
}
else {
exit();
}
//2nd condtion
if($var2 == 'run'){
echo 'run';
}
//3rd condtion
if($var3 == 'go'){
echo 'go';
}
}
**I try to Exit() First If Condition, continue to next IF Condition, But Cannot Continue next IF condition totally Exit Overall Please Fix My Problem Thankyou **
No need to use else condition if you want to run second if statement
if($var1 != '' && $var2 != '' && $var3 != '' ){
//first condtion
if($var1 == 'clear'){
echo 'clear';
}
//2nd condtion
if($var2 == 'run'){
echo 'run';
}
//3rd condtion
if($var3 == 'go'){
echo 'go';
}
}
What About the idea of this one.
<?php
$var1="exit";
$var2="run";
$var3="go";
if($var1 != '' && $var2 != '' && $var3 != '' )
{
if($var2 == 'run'){
echo 'run';
}
elseif($var3 == 'go'){
echo 'go';
}
elseif($var1 == 'clear'){
echo 'clear';
}
else {
exit();
}
}
just use only if.. use return
$var1="exit";
$var2="run";
$var3="go";
if($var1 != '' && $var2 != '' && $var3 != '' ){
//first condtion
if($var1 == 'clear'){
echo 'clear';
}else {
return;
}
//2nd condtion
if($var2 == 'run'){
echo 'run';
}else {
return;
}
//3rd condtion
if($var3 == 'go'){
echo 'go';
}else {
return;
}
}
I got an array implode variable, $varString, that is setup to return 3 separate values listed below depending on the condition.
1
2
1,2
If ($varString == 1)
{
echo 'APPLE';}
ElseIf ($varString == 2)
{
echo 'BANANA';}
ElseIf ($varString == 1,2) //throws an error.
{
echo 'APPLE and BANANA';}
How do I do this for the case of 1,2?
I tried
ElseIf ($varString == '1,2') //throws an error.
{
echo 'APPLE and BANANA';}
ElseIf ($varString == "1,2") //throws an error.
{
echo 'APPLE and BANANA';}
As 1,2 could only be understood by PHP as a string, you should change your script to this:
If ($varString == '1')
{
echo 'APPLE';
}
ElseIf ($varString == '2')
{
echo 'BANANA';
}
ElseIf ($varString == '1,2') //no it doesn't
{
echo 'APPLE and BANANA';
}
and also, string should always be in ''
ElseIf ($varString == '1,2') { echo 'APPLE and BANANA';}
When I click y link,it is going to x.Why is that ?
x
y
<?php
if(isset($_REQUEST['hello']) == 'x')
{
echo 'x';
}
else if(isset($_REQUEST['hello']) == 'y'){
echo 'y';
}
else
{
echo "else";
}
try
if(isset($_REQUEST['hello']) && ($_REQUEST['hello']) == 'x') )
The isset function returns either true or false and you are comparing that return value with strings 'x' and 'y'.
Since you are using == and not ===, true == 'x' will return ture.
To fix this first you need to check if the variable is set and only then compare it.
if(isset($_REQUEST['hello']) && ($_REQUEST['hello']) === 'x'))
isset returns true or false, in both of these examples hello is set to something, so isset would return true (which does not equate to either x or y)
Hopefully this helps.
<?php
if(isset($_REQUEST['hello']) && $_REQUEST['hello']== 'x')
{
echo 'x';
}
else if(isset($_REQUEST['hello']) && $_REQUEST['hello'] == 'y'){
echo 'y';
}
else
{
echo "else";
}
?>
isset will check whether the request is set or not returns 0 or 1
x
y
<?php
if($_REQUEST['hello'] == 'x')
{
echo 'x';
}
else if($_REQUEST['hello'] == 'y'){
echo 'y';
}
else
{
echo "else";
}
<?php $myvar = $_REQUEST['hello'];
if($myvar == 'x')
{
echo 'x';
}
else if($myvar == 'y')
{
echo 'y';
}
else
{
echo 'else';
}
?>
Try this one
I'm having some issues with this statement,
<?php
$cert_mess = $vehicle['make'];
if ($vehicle["make"] == "Honda" && $vehicle["Certified"] == "0") {
$cert_mess = "DFWCertAutos";
}
elseif ($vehicle["make"] == "Cadillac" && $vehicle["Certified"] == "0") {
$cert_mess = "DFWCertAutos";
}
elseif (!in_array($vehicle['make'], array('Cadillac','Honda') )) {
$cert_mess = "DFWCertAutos";
}
?>
<div style="font-size:10px; padding:10px; padding-top: 0px;">*This car is <?php
echo $cert_mess ?> certified.</div>
Any suggestions? currently it just displays $cert_mess as 'make' and ignores the if / else if statements.
A simpler code can be the following:
$cert_mess = $vehicle['make'];
if (($vehicle["make"] == "Honda" && $vehicle["Certified"] == "0")
|| ($vehicle["make"] == "Cadillac" && $vehicle["Certified"] == "0")
|| !in_array($vehicle['make'], array('Cadillac','Honda'))
) {
$cert_mess = "DFWCertAutos";
}
Simpler still:
$cert_mess = $vehicle['make'];
if (!in_array($vehicle['make'], array('Cadillac', 'Honda')) || $vehicle['certified'] == '0')
{
$cert_mess = 'DFWCertAutos';
}
Is there any way to go to the else if body after the if condition is sucessfully entered?

If Main IF Statement evaluates true and Inner IF Statement evalautes false then go to Main ELSE IF ladder. If Main IF Statement evaluates true and Inner IF Statement evalautes true then stop loop . If Main IF Statement evaluates false, directly go to Main ELSE IF Statement
If Main ELSE IF Statement evaluates true and Inner IF Statement evalautes false then go to Main ELSE IF ladder. If Main ElSE IF Statement evaluates true and Inner IF Statement evalautes true ,then stop loop .If Main ELSE IF Statement evaluates false, directly go to other Main ELSE IF Statements
Try this:
$success = true;
if($a == $Xaxis && $b == $yaxis) {
$zAxis = $Xaxis + $yaxis;
$success = $Xaxis != $zAxis;
}
if( ($b == $Xaxis && $a == $yaxis) || !$success) {
// do stuff here
}
Or something along those lines.
