php - Converting value of text field to negative if checkbox is clicked -

I have 10 text fields for numeric values, each has a checkbox for each check if the checkbox is checked, the text field The values ​​entered must be converted into negative values ​​and then have to be saved in the database. If checked again it should become positive.

  & lt; Td> & Lt; Input type = "text" name = "or" square = "number" maximum length = "5"? & Gt; "Id =" or "/> db   Input  & lt; td & gt; & lt; input type = "text" name = "or4" class = "num" maxlength = "5" /> gt; db & lt; ; / Td>  & lt; input type = "text" name = "or8" class = "number" maximum length = "5" /> gt; & lt; / td & gt; & Lt; td & gt; Input  and DB  
  for each text box & lt; Td> - & lt; input type = "checkbox" name = "orneg1" class = "check1"   
 check box "id =" org "/> 
 & lt; td & gt; - & lt; input type = "Org2" class = "check2" /> gt; & lt; / td> & lt; td & gt; - & lt; input type = "checkbox" name = "org4" class = "Check 3" /> gt; & lt; / td> & lt; td & gt; - & lt; input type = "checkbox" name = "org8" class = "check4" / & gt; & lt; / Td> & lt; td & gt; - & lt; input type = "checkbox" name = "org5" class = "check5" /> & Lt; / Td>   
 
 This can work:  
  $ ('Input [type = checkbox]' '(app (' (i) ') (eq (' (i) ') (app ($ (this) .attr (' checked ') ==' check ') { Var inputText = $ ('input [type = text]: eq (' + i + ')' '; var inputValue = parseInt (inputText.val (), 10); if (input value> gt; 0) {inputValue = '- InputText.attr (' value ', input value);}});
