Parse Error escape PHP inside Jquery and PHP
Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in ...
This is the error that I'm getting
<?php
function my_custom_js() {
echo " <script>" ;
echo " jQuery(document).ready(function(){
jQuery('#secondary-front .first h3').addClass('
<?php $options = get_option('mytheme_theme_options');
if(!empty($options['first_widget_icon'])) echo $options['first_widget_icon']?> ');
jQuery('#secondary-front .second h3').addClass('<?php $options = get_option('mytheme_theme_options');
if (!empty($options['second_widget_icon'])) echo $options['second_widget_icon'];?>');
jQuery('#secondary-front .third h3').addClass('<?php $options = get_option('mytheme_theme_options');
if (!empty($options['third_widget_icon'])) echo $options['third_widget_icon'];?>');
});
";
echo "</script> ";
}
add_action('wp_head', 'my_custom_js');
?>
I cannot get this code to escape correctly, i have php > jquery > php
The problem is your quotes ( " ) don't weigh up on both sides. That said, when I've gone to investigate the problem, I've noticed worse things with your code, so I've rewritten it entirely for you:
<?php
function my_custom_js() {
$options = get_option('mytheme_theme_options');
echo "<script>
jQuery(document).ready(function(){
jQuery('#secondary-front .first h3').addClass('" . ($options['first_widget_icon'] ?: NULL) . "');
jQuery('#secondary-front .second h3').addClass('" . ($options['second_widget_icon'] ?: NULL) . "');
jQuery('#secondary-front .third h3').addClass('" . ($options['third_widget_icon'] ?: NULL) . "');
});
</script>";
}
add_action('wp_head', 'my_custom_js');
?>
One thing I've done is moved $options = get_option('mytheme_theme_options'); to the top. I've also removed the repeated calls to this. Also, that's had the knock-on effect that the echo can be made all in 1 statement, with clever use of the ternary operator.
echo ($something ?: NULL); means if $something exists, echo it, else echo nothing.
Using the ternary operator with the ?: shorthand requires PHP >= 5.3.0
For versions below this, simply fill in the middle part, ie:
// PHP >= 5.3.0
($options['first_widget_icon'] ?: NULL)
// PHP < 5.3.0
($options['first_widget_icon'] ? $options['first_widget_icon'] : NULL)
Of course, the code might need tweaking to your liking, but it should be a basis for improvement.
