I have form with the option to add more fields. I'd like to know if i could print the individual values of a foreach loop. eg. if the person added to forms and i want to print the second value how would i do that ? So Far what i have tried only printed the first Character.
HTML
<form action="careerHistoryCon.php" method="post" enctype="multipart/form-data">
<label for="industry[]">Industry Segmentation</label>
<input type="text" name="industry[]" id="" placeholder="Finance / Insurance ...."><br>
<p>To add another feild <a href="#" id="addMore">Click here</a> </p> <br><br>
</form>
JQ
$("#addMore").click(function(){
$(".form-group:last").clone().appendTo(".wrapper");
});
PHP - Problem here
if ($_SERVER["REQUEST_METHOD"] == "POST") {
if (isset($_POST['submit'])){
$industry= $_POST['industry'];
foreach ($industry as $key => $value) {
echo $value[0]. '<BR>';
echo $value[1]. '<BR>';
}
}
You are pretty near to the solution. Using foreach on an array gives you the index as key.
foreach ($industry as $key => $value) {
if($key == 1) echo $value; // array starts with 0, so 1 is the second element.
}
or you can use an iterator
// using foreach
$i = 0;
foreach ($industry as $key => $value) {
if($i == 1) echo $value;
$i++;
}
//using for
for($i = 0; $i < count($industry); $i++) {
if($i == 1) echo $industry[$i];
}
btw. since $value is the input string of the user, $value[0] would just be the first letter the user entered. Because a string is just an array of chars.
