php - I have two similar functions while one output changes and the other doesn't -


This code uses html, php, and laravel. At first, a 'vaccine' does not change in value. The second one changes the 'NTK' value, but eventually my output on the webpage allows me to check the check box for some reasons. In fact, there is hope that someone can help me because I do not know how this is possible. Especially when I uncheck the wrong check box in $ ntk

This is my form: 

  & lt ;? Php $ tk = session :: is ('tk')? Session :: Mill ('vaccine'): 1; Var_dump ($ t); If ($ tk == 1) {$ tk = 'true'; } And {$ tk = 'false'; } $ Tk_name = 'tk:'; Var_dump ($ tk_name); Var_dump ($ t); $ Ntk = session :: is ('NTK')? Session :: Mill ('NTK'): 0; Var_dump ($ NTK); If ($ ntk == 1) {$ ntk = 'true'; } And {$ ntk = 'false'; } $ Ntk_name = 'ntk:'; Var_dump ($ ntk_name); Var_dump ($ NTK); ? & Gt; {{Form :: open (array ('url' = & gt; 'envulen'))}} < Table & gt; & Lt; TR & gt; & Lt; TD & gt; {{Form: submit ('toepassen')}} & lt; / Td> & Lt; TD & gt; {{Form :: checkbox ('vaccine', 1, $ vaccine)}} sedative (vaccine) & lt; Br> {{Form: Checkbox ('NTK', 1, $ NTK)}} Nit-Tejdrict (NTK) & lt; Td> & Lt; / TR & gt; & Lt; / Table & gt; {{Form :: close}}}   
 Here is my control code:  
  if (isset ($ _ POST ['tk'])) {$ Vaccines = $ _POST ['vaccine']; Session: put ('vaccine', $ vaccine); } And {$ tk = 1; Session: put ('vaccine', $ vaccine); } If (pret ($ _ POST ['NTK'])) {$ ntk = $ _POST ['NTK']; Session: put ('NTK', $ NTK); } And {$ ntk = 0; Session: put ('NTK', $ NTK); }    
 
 
 You are using:  
  if ($ tk == 1) {$ tk = 'true'; } And {$ tk = 'false'; }   
 In this case,  $ tk  is always correct because  true  is  string  not  Boolean value  and when you use the  Boolean  value as  $ tk , it comes out of  true  Because it is a  true  value, for example:  
  $ tk = 'false'; Echo !! $ Vaccines; // 1 = true   
 Anyway, this problem is, your  $ tk  does not contain the string  Boolean  and the right to assign Method is a  boolean value :  
  $ k = TRUE; Without the Qoutes   
 but you do not need to assign  TRUE  or  FALSE  to  $ tk  It: Enter the code here ($ tk == 1) {$ tk = true; } And {$ tk = false; }   
 Since,  0  a  falsi  value  FALSE  and  1  So you can use directly  $ tk :  
  {{form :: checkbox ('tk', 1, $ tk)}}   
  $ tk  1  or  0 ) > This will be either:  
  {{form :: checkbox ('vaccine', 1, 1)}} checked {{form :: checkbox ('vaccine', 1, 0) ))}} // Unchecked   
 Therefore, if  $ tk  contains  1  then the  checkbox  Will be  checked The  and if  0  so that  will not Czech .
