php - How do you fix this notice: Uninitialized string offset: 0 with stripslashes? -


when upload theme wordpress, notice in options page:

uninitialized string offset: 0

this code:

function name_of_function ( $args ) {     extract( $args );     $option_name = 'the_theme_options';     $options = get_option( $option_name );     switch ( $type ) {           case 'text':             $options[$id] = stripslashes( $options[$id] );             $options[$id] = esc_attr( $options[$id] );             echo "<input class='regular-text$class' type='text' id='$id' name='" . $option_name . "[$id]' value='$options[$id]'>";             echo ( $desc != '' ) ? "<br><span class='description'>$desc</span>" : "";         break;

when save, notice goes away.

i tried adding isset, (i getting notice:undefined index @ first):

$options[$id] = stripslashes( isset( $options[$id] );

the errors go away fails save.

then added isset following line:

$options[$id] = esc_attr( isset( $options[$id] ) );

still didn't work.

i tried removing line still errors:

$options[$id] = stripslashes( $options[$id] );

i tried this:

if ( isset( $options[$id] ) {     $options[$id] = stripslashes( $options[$id] ); }

i'm aware of things tried don't make sense.

i've been searching hours. read docs. can't seem find solution this.

$options string in context, not array. trying treat array, doesn't work. logic in code never work; it's not clear you're trying $options[$id].

the reason get

uninitialized string offset: 0

is $id not initialized anywhere, php treats 0. saying, "look @ string ($options) , array value @ key 0," , php throws hands because doesn't make sense.

your various solutions won't work several other reasons. stripslashes( isset( $options[$id] ); fails because (1) $options[$id] doesn't exist , (2) stripslashes() takes string parameter, handing boolean value. same problem esc_attr( isset( $options[$id] ) );

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
