php - input field: store decimal values with comma instead of a point in mysql database -


i have input field price. entered value stored database, example 13,99.

in mysql database field has type decimal(10,2). happens price stored correctly database if user types 13.99 point instead of comma. if user types 13,99 stored 13.00.

what should change in code, user can type 13,99 , stored correctly database?

<?php ...     if ($valid) {         $pdo = database::connect();         $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);         $sql = "update products  set price =? id = ?";         $q = $pdo->prepare($sql);         $q->execute(array($price,$id));         database::disconnect();         header("location: index.php");     } } else {     $pdo = database::connect();     $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);     $sql = "select * products id = ?";     $q = $pdo->prepare($sql);     $q->execute(array($id));     $data = $q->fetch(pdo::fetch_assoc);     $price = $data['price'];      database::disconnect(); } ?> ...    <div class="control-group <?php echo !empty($priceerror)?'error':'';?>">                     <label class="control-label">preis</label>                     <div class="controls">                         <input class="form-control" name="price" type="text"  placeholder="price number" value="<?php echo !empty($price)?$price:'';?>">                         <?php if (!empty($priceerror)): ?>                             <span class="help-inline"><?php echo $priceerror;?></span>                         <?php endif;?>                     </div>                   </div>

try

...  if ($valid) {         $price = str_replace(",",".",$price);         $pdo = database::connect();         $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);         $sql = "update products  set price =? id = ?";         $q = $pdo->prepare($sql);         $q->execute(array($price,$id));         database::disconnect();         header("location: index.php");     } } else {     $pdo = database::connect();     $pdo->setattribute(pdo::attr_errmode, pdo::errmode_exception);     $sql = "select * products id = ?";     $q = $pdo->prepare($sql);     $q->execute(array($id));     $data = $q->fetch(pdo::fetch_assoc);     $price = $data['price'];      database::disconnect(); } ...

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
