How to call a function using Echo?

Copy linkTweet thisAlerts:
Dec 02.2015

I have this function:

[LIST]

  • [*]

    getbgc()


    • [/LIST]

    I’m trying to call it using an echo statement, but I can’t seem to get it right. Here’s what I have:

    [code=php]echo “<tr style=”.getbgc($i).”>
    <td style=’width:auto’>”.$row[0].”</td>
    <td style=’width:auto’>”.$row[1].”</td>
    … etc[/code]

    To me, that looks right. But it isn’t being called. The function only serves to alternate two colors on the table rows, but they stay white throughout. Can anyone tell me what I’m doing wrong here?

    @ginerjmDec 02.2015 — 1 - do you have error checking turned on?

    2 - does this function return a scalar value?

    3 - if you would begin to use css, making that width:auto a td setting would save you a lot of needless typing.

    @NogDogDec 02.2015 — What you have looks fine -- assuming the function actually returns something? I.e.: you want it to return the string to be output, not do an echo inside the function itself.

    function header(){

    echo "

    <script src='<?php echo node_dir ?>/nav.min.js'></script>

    ";

    }

    I can call this node_dir function from within a php echo, or alternately output:

    <script src='<?php echo node_dir ?>/nav.min.js'></script>

    from the header function.
