Specifying ID in Mysqli query in php -

-

i'm working on cms site, i've got blog posts store in database. can create, edit , delete them. there's issue though when want edit them. can't specify clause in update query match id of blog post i'm trying edit!

suppose i've got blog post id of '5'. if write code it, works way should.

 $sqledit = "update paginas set message='$_post[message]' id= $_post[id]";

but don't want edit blog post #5, want edit blog post i'm updating. seems me should work,

where id= $_post[id]";

... doesn't.

that throws me undefined id error. shouldn't because can delete blog posts exact same way particular code:

$sqldel = "delete `paginas` id= $_post[id]";

this allow me to.

the code below on blog page, edit query in own edit.php page

        if (isset($_post['edit'])) // if pressed, execute          {           echo          '<br><br>  <div class="blogscript">          <form action="edit.php" method="post">edit stuff<br>                   <input type="text" placeholder='. $pagetitle . ' ><br><br>                   <textarea id="message2" name="message">&lt;p&gt;' . $message . '&lt;/p&gt;</textarea><br>                    <input type="submit" name="editsubmit" value="confirm" />         <input type="hidden" name="id" value="' . $id . '">.            </form></div>';         }

i forward tips should try out.

edit:

this edit.php page

<?php   $db_host = "localhost";   $db_user = "root";   $db_pass = "";   $db_name = "cmsbase";    $mysqli_con = new mysqli($db_host,$db_user,$db_pass,$db_name);       if($mysqli_con->connect_errno)      {          die("error : -> ".$mysqli_con->connect_error);      }        $sql = "update paginas set message='$_post[message]' id= $_post[id]";      if ($mysqli_con->query($sql) === true) {     echo "";     } else {     echo "error: " . $sql . "<br>" . $mysqli_con->error;     }     $mysqli_con->close(); //close connection       echo "<script>alert('edited');location.href='index.php';</script>";  ?>

edit: var_dump contains this var_dump says

in order values present in $_post, need have element (e.g. <input>, <select>, <textarea>) inside form name attribute set $_post key want.

you can add hidden input form id.

<input type='hidden' name='id' value='" . $id . "'>

assuming getting $message variable shown in form code selecting database, should able id there well, or potentially $_get if how determine post being displayed.

asp.net mvc - breakpoint on javascript in CSHTML? -

-
i have .cshtml file has javascript tag. within script tag have few lines of javascript. first line of javascript refers property in @viewbag. other javascript lines plain script without mvc related references. observation: can place breakpoints (visual studio 2015) on each of these javascript lines. however, breakpoints has white dot in center of breakpoint symbol (red circle) except line @viewbag reference (this particular line not have white dot in center). it seems breakpoint without white dot hit during run-time. question: can explain going on here? white dot mean? why plain red breakpoint line line hitting breakpoint? the visual studio debugger expecting debug actual server-side code within .cshtml file opposed client-side javascript within it. iirc, visual studio allow debug javascript code expected in internet explorer (and possibly edge), other browsers want use either third-party tool or developer tools (f12) within browser. an easy approach take advant...
