why the if else statement does not run the else statement? - php

Question

I have a problem with my if and else statement in PHP where it never runs the else statement.
The input form is in HTML:
<input type="radio" name="marital_stat" id="single" value="single" />Single
<input type="radio" name="marital_stat" id="married" value="married" />Married
<input name="age" type="text" size="5" maxlength="3" placeholder="30" required/>
<input name="work" type="radio" id="employee" value="employee" />Employee
<input name="work" type="radio" id="own" value="own" />
Own Business
<input name="work" type="radio" id="jobless" value="jobless" />Jobless
<input name="place" type="radio" id="urban" value="urban" />Urban
<input name="place" type="radio" id="rural" value="rural" />Rural</td>
Here is the PHP Code:
if ($marital_stat == 'married')
{
if ($age >= 18 || $age < 59)
{
if ($work == 'jobless')
{
if ($place == 'rural') { $loan_credibility == 5; }
}
}
}
else if ($marital_stat == 'single')
{
if ($age >= 18 || $age < 59)
{
if ($work == 'employee')
{
if ($place == 'rural') { $loan_credibility == 1; }
}
}
}
Here is a condition that will display some output:
$A = 'positive';
$B = 'negative';
if ($loan_credibility == 5 ){
echo $B ;}
else{
echo $A;
}

Answer 1

As I see you make $loan_credibility == 5; or 1; the == only used in equality statement it checks the two sides if they equal and you have to use = to set value, not == so it will be $loan_credibility = 5; or 1;

Answer 2

You have no else clause (which logically is necessary when using else if)...
if (condition) {
code to be executed if condition is true;
} elseif (condition) {
code to be executed if condition is true;
} else {
code to be executed if condition is false;
}
Do any of the following (#1 or #2 make the most sense)...
Make your else if into a separate if block
Change else if to else
Or add an else clause
Also, as #Mohamed Belal pointed out, when setting variables use = not ==.
So two things to fix your problem: 1) if-else if-else logic and 2) = vs ==...
if ($marital_stat == 'married')
{
if ($age >= 18 || $age < 59)
{
if ($work == 'jobless')
{
if ($place == 'rural') { $loan_credibility = 5; }
}
}
}
if ($marital_stat == 'single')
{
if ($age >= 18 || $age < 59)
{
if ($work == 'employee')
{
if ($place == 'rural') { $loan_credibility = 1; }
}
}
}
