When building software user interfaces, I create HTML forms to manage any app settings. I’ll usually have a few text and radio inputs like this:<\/p>\n

\"settings<\/p>\n

Using PHP, I grab a database record and access its properties to populate the form. Filling out the text inputs is straight-forward:<\/p>\n

<?php $clickToCallRecord = $db_service->getClickToCallRecord($installation_complete_id); ?>\n\n<div class=\"form-group\">\n    <label>Phone number:<\/label>\n    <input class=\"form-control\" type=\"tel\" name=\"phone_number\" value=\"<?php echo $clickToCallRecord['phone_number']; ?>\" placeholder=\"(123)-456-7890\">\n<\/div>\n<div class=\"form-group\">\n    <label>Message:<\/label>\n    <input class=\"form-control\" type=\"text\" name=\"message_text\" value=\"<?php echo $clickToCallRecord['message_text']; ?>\" placeholder=\"Call Us Now\">\n<\/div>\n<div class=\"form-group\">\n    <label>Background Color:<\/label>\n    <input class=\"form-control\" type=\"text\" value=\"<?php echo $clickToCallRecord['bg_color']; ?>\" name=\"bg_color\">\n<\/div>\n<\/pre>\n
Checking the correct radio input requires our code to evaluate the data value. I add a PHP variable to each of the inputs as attributes. Those variables will render to either “checked” or blank:<\/p>\n
<?php\n    $top_checked = \"\";\n    $bottom_checked = \"\";\n    $position = $clickToCallRecord['position'];\n    if($position == \"top\"){\n        $top_checked = \"checked\";\n        $bottom_checked = \"\";\n    }else{\n        $top_checked = \"\";\n        $bottom_checked = \"checked\";\n    }\n\n    $show_checked = \"\";\n    $hide_checked = \"\";\n    $display = $clickToCallRecord['display'];\n    if($display == \"show\"){\n        $show_checked = \"checked\";\n        $hide_checked = \"\";\n    }else{\n        $show_checked = \"\";\n        $hide_checked = \"checked\";\n    }\n\n?>\n\n<div class=\"form-group\">\n    <label>Position:<\/label>\n    <div>\n        <div class=\"form-check form-check-inline\">\n          <input <?php echo $top_checked; ?> class=\"form-check-input\" type=\"radio\" name=\"position\" value=\"top\">\n          <label class=\"form-check-label\" for=\"matchtype\">Top<\/label>\n        <\/div>\n        <div class=\"form-check form-check-inline\">\n          <input <?php echo $bottom_checked; ?> class=\"form-check-input\" type=\"radio\" name=\"position\"  value=\"bottom\">\n          <label class=\"form-check-label\" for=\"matchtype\">Bottom<\/label>\n        <\/div>\n    <\/div>\n<\/div>\n<hr \/>\n<div class=\"form-group\">\n    <label>Display:<\/label>\n    <div>\n        <div class=\"form-check form-check-inline\">\n          <input <?php echo $show_checked; ?> class=\"form-check-input\" type=\"radio\" name=\"display\" value=\"show\">\n          <label class=\"form-check-label\" for=\"matchtype\">Show<\/label>\n        <\/div>\n        <div class=\"form-check form-check-inline\">\n          <input <?php echo $hide_checked; ?> class=\"form-check-input\" type=\"radio\" name=\"display\"  value=\"hide\">\n          <label class=\"form-check-label\" for=\"matchtype\">Hide<\/label>\n        <\/div>\n    <\/div>\n<\/div>\n<\/pre>\n
This example comes from a Shopify app that helps stores increase conversions by adding a UI element prompting customers to call a phone number.<\/p>\n","protected":false},"excerpt":{"rendered":"
