Problem using code in ContactForm

    Hi,

    I had Contact Form routines in my theme footer.php. But suddenly, it stopped working. I researched and had recommendations of this plugin.

    After updating and saving the snippet, it does not make the right consistency. I can not get back to working as the routine was in footer.php. What will be my mistake?

    Snippet updated.

    Name: OnlyNumber

    Code:

    1 add_action(‘wp_footer’, ‘OnlyNumber’);
    2
    3 ?>
    4 <script>
    5 function OnlyNumber(num) {
    6 var er = /[^0-9.]/;
    7 er.lastIndex = 0;
    8 var campo = num;
    9 if (er.test(campo.value)) {
    10 campo.value = “”;
    11 }
    12 }
    13 </script>
    14 <?php

    In the ContactForm, the field that makes the “call” to the “OnlyNumber” routine:

    <input class=”num_placa” onkeyup=”OnlyNumber(this);” maxlength=”4″ minlength=”4″ size=”4″ type=”text” />

    That is, it accepts letters, numbers, .etc, what the routine would prevent.

    Thank you very much

    Hi José,

    In order to output JavaScript or HTML code in your page footer, you’ll need to wrap it all in a PHP function:

    add_action( 'wp_footer', function () { ?>

<script>
function OnlyNumber(num) {
	var er = /[^0-9.]/;
	er.lastIndex = 0;
	var campo = num;
	if (er.test(campo.value)) {
		campo.value = "";
	}
}
</script>

<?php } );

    Give the above code a try; I think it should work much better.
