$connB = new ProductDAO();
$connB->Connect();
$pro_query = "SELECT * FROM Cart WHERE `Email`='$user_email';";
$db_result = $connB->ExecSQL($pro_query);
$html_result = '<div data-role="content"> <ul data-role="listview" data-theme="b"> ';
$html_result .= '<form action="PreviouscartProduct.php" method="POST"/>';
while($row_array = $db_result->fetch_array(MYSQLI_ASSOC))
{
$Id= $row_array['Id'];
$Date= $row_array['Date'];
//$html_result //
$html_result .="<li><a href='PreviouscartProduct.php'>Cart number: $Id from Date: $Date><input type='hidden' name='Id' value'<?=$Id?>'</input></a></li>'";
$html_result .= '<a onclick="this.form.submit();" </a>;
}
$html_result .= '</form>';
$html_result .= ' </ul> </div>';
$connB->Disconnect();
return $html_result;
}
//display all carts
$func_result = ShowAllCarts($Email);

Answer 1

You need to use a checkbox element:
$html_result .="<li>"
."<checkbox name='cartItem[$Id]' value='$Date'>"
. "Cart number: $Id from Date: $Date"
. "</li>'"
;
Then, in PreviouscartProduct.php, you'd itera over cartItem:
$cartItems = $_POST[ 'cartItem' ];
foreach( $cartItems as $id => $date ) {
... do something ...
}
In case you'd like to take exactly one item, why not use this:
$html_result .="<li>"
. "<a href='PreviouscartProduct.php?cartID=$Id&date=$Date'>"
. "Cart number: $Id from Date: $Date"
. "</a>"
. "</li>'"
;

There's a bunch of HTML syntax errors in this, check the output in a validator
For a start, your opening a tag doesn't close after this.form.submit();, it should read
$html_result .= '<a onclick="this.form.submit();">Anchor Text Here</a>';
Edit :
the anchor element needs to reference the form. Give the form element a name attribute and use something like
onclick="document.nameattributehere.submit();return false"
on the link.
End edit.
Also, in the line above, you're already using the PHP parser when you get to the value attribute of your input, so there is no need for the
<?= and ?>
Finally, in the same tag, you don't need a closing input tag
</input>
Just close the opening tag with
/>
That's just glancing, run the validator for other errors and I'm sure the problem will be clearer.
